Hey,
we use no caching at the moment. Pure hosting, pure wordpress. I know that there is an image caching function active delivered through the theme itself. But I can´t stop it.
What I did now is to add the following line to my wp-config.php file:
define( 'ENABLE_CACHE', false );
But important: When I check the file system I see the following cache folders:
./wp-content/plugins/wp-statistics/includes/vendor/psr/cache
./wp-content/plugins/litespeed-cache/tpl/cache
./wp-content/themes/yootheme/cache
wp-statistics could be temporary deactivated if necessary
litespeed-cache is not active. Did you installed this? I never used this plugin before…
yootheme is the caching function of the theme itself.
I hope this helps a little bit!
