Plugin compatibility

We do not restrict any plugin usage, however, not all plugins are compatible. Plugins that require writing access to wp-config.php file are not compatible, in most cases this kind of plugins are for security, performance, cloning, restoring or similar but Closte has all these features built-in. Litespeed cache must be used for full-page caching for platform compatibility and better support.

Must use plugins

  • Any caching plugin even those not compatible with some of our monitoring features. Litespeed cache, WP-Rocket, WP Fastest Cache, W3 Total Cache and FlyingPress caching plugins are compatible with our monitoring statistics e.g cache-hit, cache-miss and not-cacheable logs.
  • Closte built-in MU plugin

Highly recommended to use

  • Use our backup system, not any other.
  • Use our built-in server-side security.
  • Use our free migration service.

Highly recommended NOT to use

  • Do not use plugins that send a non-cacheable PHP request on every visit e.g Analytics plugins or Advertising plugins. Those are CPU/Concurrency killers and there are tons of better alternatives.
  • Do not use any backup plugin or service.
  • Do not use any plugin for cloning, restoring, migrating and so on, use our features or our free migration service.

Not compatible plugins

  • Any plugin that throws a fatal error because requires writing access to the wp-config.php file without giving you the opportunity to manually update the wp-config.php file.
  • Any plugin that requires writing access to WordPress core files, in most cases, these are plugins for cloning or restoring a backup.
