How does Page Cache work?

Enable this app for better page caching. Caching (stored for 30 days), cleared via CRON after 30 days for server optimazation. Cached files autoupdating as changes are published. Generate posts and page into cached files from the database. Cached Pages get a HTTP header and HTML comment.

How does Emoji Disable work?

Removal of WordPress Emoji library, in performance tests this shows to slow down websites, not everyone uses comments so the emoji library should be optional.

Will this work with my existing plugins?

Yes, it should as you can easily enable or disable certain features from the dashboard.

Can I alter the code in the plugin?

To provide the best support to all users and to have synchronized changes to mirror WordPress updates our suggestion is to not alter our code. However we do offer professional services to build custom WordPress integrations and features, please contact us here.

What version of PHP do I need?

Ideally PHP 7.0+, but our software is built with WordPress hooks so as long as your site runs WordPress 6.0+ it should be supported.

Where can I learn about a proper installation?

You can read our docs here, and also subscribe to our newsletter for product updates.

I have tested this intensively and all I experienced were bug after bug and it made my site’s performance even worse. I have tested this in comparison to Litespeed cache and WP-Rocket. Unfortunately, I purchased the LTD of the plugin on DealMirror which I regretted. This has been the worst product I’ve ever purchased. Plus, despite getting the LTD, they have canceled my license without prior notice and reason. I have emailed {their support} about it but he is unresponsive. In short, the LTD became a money grab for Deal Mirror and Devland.
