If you activate 2 caching plugins (or at least the functionality) at the same time, this might cause a fatal error and break your site.
Follow these instructions to recover your site:
wp-config.php
.define('WP_CACHE', true);
, delete it, save the file and upload it back via FTP.wp-content
and delete the file advanced-cache.php
If the error comes back before you had a chance to do this:
wp-content/plugins
, and rename the folders of all caching plugins (for example by adding a -
).wp-content/plugins
, and rename the folders of all caching plugins back to their original names.WP-Optimize is compatible with all web servers, including:
However, only Apache makes it possible for a WordPress plugin to turn on Gzip compression and static caching headers; thus, on other webservers, WP-Optimize can only test and advise whether these beneficial features are active, but cannot itself turn them on.
To find out if this is the issue, you can search the code for ob_gzhandler
or gzencode
. If any of those two strings is found (outside of WP-Optimize), it could be the source of the issue.
Go to WP-Optimize -> Cache and enable caching
You’re good to go!
If you run an e-commerce, have a custom login page or any page that has dynamic content, you might want to exclude certain urls from the cache. See Excluding an url from the cache for more details.
