General WordPress Cache Plugin FAQs
What does Holographic Extreme Cache actually do?
Holographic Extreme Cache helps WordPress serve suitable pages faster by using cached page output. Instead of making WordPress, PHP and the database rebuild the same page on every suitable visit, the plugin can deliver a prepared version when caching is safe.
Will a cache plugin make every WordPress site faster?
Usually, page caching helps because it reduces repeated server work. However, the final result depends on the theme, plugins, hosting, images, scripts, fonts and whether the pages suit caching. Therefore, caching gives most sites a strong starting point, not a complete fix for every performance issue.
Can caching break contact forms, menus or checkout pages?
Poorly configured caching can cause problems on pages that need to stay dynamic. For example, contact forms, basket pages, checkout pages, account pages and some script-heavy areas need careful handling. Because of this, Holographic Extreme Cache uses safer cache rules, while the Professional version adds more controls for sensitive pages.
Do I need to understand technical caching before using it?
No. The plugin makes cache status, setup checks and cache controls easier to understand inside WordPress. Even so, you should still test important pages after enabling caching, especially forms, checkout flows, account pages and anything that changes for each visitor.
Should I clear the cache after editing a page?
Usually, no. Holographic Extreme Cache clears or refreshes cached content when normal WordPress changes happen. For example, editing a page or post should not normally require you to clear the whole cache by hand.
However, a manual cache clear can still help after larger site changes, theme edits, menu changes, layout changes, plugin changes or troubleshooting. In addition, the Professional version adds smarter purge and preload tools so related pages can refresh and rebuild more carefully.
Can I use it with another cache or optimisation plugin?
It is usually better to avoid running several plugins that control the same caching or optimisation features. For example, two page cache plugins, two image conversion tools or two JavaScript delay systems can conflict. If you already use another optimisation plugin, review overlapping features carefully before enabling similar settings.
Will logged-in users see cached pages?
Logged-in areas need more cautious handling because the content may be personal, account-based or admin-only. As a result, cache rules should treat logged-in users and account pages more strictly than ordinary public pages.
What should I test after enabling caching?
Test the homepage, important service or sales pages, contact forms, menus, search, account pages and checkout flows if your site sells online. In addition, open the site in a private browser window so you can check the public visitor experience rather than only the admin view.
Free WordPress Cache Plugin FAQs
What is included in the free version?
The free version gives you the page cache foundation. It covers essential static page caching, cache clearing, basic preload tools and simple setup checks. Therefore, it gives smaller WordPress sites, blogs and simple business websites a practical starting point.
Is the free version enough for a small business website?
For many simple business websites, the free version may be enough to start with. However, if the site uses WooCommerce, lots of images, complex scripts, client reporting, Cloudflare, CDN delivery or sensitive pages that need more control, the Professional version will usually fit better.
Does the free version include image optimisation?
The free version does not include image optimisation. If you need WebP conversion, AVIF conversion, existing image scans or image conversion reports, use the Professional version. The free plugin focuses on the cache foundation rather than image processing.
Does the free version include Cloudflare or CDN tools?
The free version focuses on local WordPress page caching, so it does not include Cloudflare or CDN controls. By contrast, the Professional version adds Cloudflare cache purging, simpler Cloudflare setup, CDN URL rewriting and related delivery checks.
Can I upgrade later without rebuilding my site?
Yes. The Professional plugin works as an upgrade around the free cache engine. Install the free plugin first, then add the paid plugin and licence when you need the Professional features.
Is the free version just a trial?
No, the free version is a usable cache plugin for essential page caching. However, it does not include the full Professional toolkit, so larger or more commercially important sites may outgrow it.
Where can I read more about the free version?
The free version has its own page with a clearer breakdown of what it includes, what it suits, and when an upgrade may make sense.
Professional WordPress Cache Plugin FAQs
When should I choose the Professional version?
Choose Professional when caching has become part of how you actively manage a website. For example, it fits business websites, WooCommerce stores, image-heavy sites, content-heavy sites, client projects and sites that need clearer diagnostics or safer optimisation controls.
What does Professional add over the free version?
Professional adds Safe Mode, per-page optimisation profiles, advanced exclusions, WooCommerce diagnostics, image conversion, WebP, AVIF, Critical CSS, JavaScript controls, font tools, Cloudflare support, CDN rewriting, reports, before-and-after checks, rollback tools and database cleanup.
Is Professional safe to use on WooCommerce?
Professional includes WooCommerce-aware diagnostics and checkout-safe handling to reduce risk around cart, checkout, account and product areas. However, you should still test every store after enabling cache or optimisation settings because themes, payment plugins and checkout customisations can behave differently.
Will image conversion use an external service or credits?
Professional image conversion works locally on the site’s own hosting where the required server support exists. Therefore, it does not rely on external image credits, conversion tokens or per-image charges.
What happens if my server does not support WebP or AVIF conversion?
Image conversion depends on the hosting environment. If the server lacks the required image library or format support, leave those conversion features disabled. In that situation, you can still use the other Professional performance features that do not depend on that server capability.
Should I enable every Professional feature at once?
No. Work in stages instead. Start with page caching, then test important pages. After that, enable image, CSS, JavaScript, font, CDN or database features one area at a time so you can see what changed and reverse settings more easily if needed.
What is Safe Mode for?
Safe Mode lets you disable riskier Professional optimisation while keeping page cache active. For example, it can help while you troubleshoot scripts, layout issues, checkout behaviour or theme compatibility.
How does smart purge help after editing content?
Smart purge refreshes related pages after content changes. For instance, editing a product, post or page may also affect archives, category pages, menus or listing pages. As a result, smart purge helps more than only clearing the single page that changed.
Does Professional work with Cloudflare?
Yes. Professional includes Cloudflare cache purging and simpler Cloudflare setup by domain. This helps local WordPress cache clearing work more cleanly with Cloudflare when your site uses it.
Do I need a CDN to use the Professional version?
No. CDN URL rewriting and CDN checks help sites that already use a CDN, but the rest of the Professional features do not require one. In other words, you can still use cache controls, image tools, diagnostics, reports and other optimisation features without a CDN.
What are rollback tools for?
Rollback tools help you recover from optimisation changes that cause problems. For example, if a JavaScript, CSS, font or image setting causes a visual or functional issue, rollback tools give you a safer route back than trying to remember every setting manually.
Where can I see the full Professional feature list?
The Professional page lists the full paid feature set in more detail, including cache safety, image optimisation, frontend optimisation, smart purge, Cloudflare, CDN, diagnostics and maintenance tools.
Licence, Pricing And Purchase FAQs
Does every Professional licence include the same features?
Yes. Every Professional licence includes the full Pro feature set. The licence tier controls how many websites you can activate, not which Professional features you can use.
Where can I check the current price?
The pricing page shows the current prices and licence options. Because prices, offers and licence options may change, use the pricing page as the source for current purchase details.
Do I need the free plugin as well as the Professional plugin?
Yes. The Professional plugin works as an upgrade around the free cache engine. Install the free version first, then add the Professional plugin and activate your licence.
Can I use one licence on more than one website?
That depends on the licence tier you purchase. The pricing page explains the available options and shows how many websites each licence supports.
Still Deciding Which Version Fits?
Start with the free version for essential WordPress page caching, or choose Professional if you need safer optimisation controls, image conversion, WooCommerce diagnostics, Cloudflare support, reports and rollback tools.
