Plugin is not working properly

Update: I changed the permission of the cache folder to 777, and the plugin started working.

After all, permission must be 777 or 755 in the cache folder? In another question I asked, you answered me that the correct permission is 755, but this setting is not allowing the plugin store the cached version of the pages inside the cache folder.

Ok, permission 755, in my case, does not allow the cache to be created and stored in the folder ‘all’. Is there any problem with leaving the permission of the cache folder in “777”?

Ok friend, but as I said in another post, permission 777 is applied only in the “cache” folder. The ‘all’ folder and all the cache that is stored in it remains with the permissions 755.

If the permission of the “cache” folder is set to 755, the cache does not work.
