Updating modules and themes requires ftp access to your serve
Consider deleting the contents of the “Rejected User Agents” text box and allow search engines to cache files for you.Preload as many posts as you can and enable “Preload Mode”.The plugin serves cached files in 3 ways (ranked by speed): Garbage collection is the act of cleaning up cache files that are out of date and stale.There’s no correct value for the expiry time but a good starting point is 1800 seconds.There are now REST API endpoints for accessing the settings of this plugin.You’ll need to be authenticated as an admin user with permission to view the settings page to use it.The plugin should clean up most of the files it created and modified, but it doesn’t as yet remove the mod_rewrite rules from the .htaccess file.
If you don’t care about sidebar widgets updating often set the preload interval to 2880 minutes (2 days) so all your posts aren’t recached very often.When the preload occurs the cache files for the post being refreshed is deleted and then regenerated.Afterwards a garbage collection of all old files is performed to clean out stale cache files.You can generate cached files for the posts, categories and tags of your site by preloading. You can be informed on garbage collection job progress.Preloading will visit each page of your site generating a cached page as it goes along, just like any other visitor to the site. There’s no right or wrong settings for garbage collection. If your site gets regular updates, or comments then set the timeout to 1800 seconds, and set the timer to 600 seconds.
