I keep having the same problem reported by friend up. For example, every time I go to clean the cache, the plugin reports that it is not possible due permission from the cache folder be set to 755.
I change to 777 and the plugin normally works in clearing the cache, and after the cleaning process is finished, I change the permission to 755 again.
That’s right, this is exactly how the plugin works?

The friend just made ??a mistake regarding the following information: it is not necessary to change the permission of the folder with the name ‘all’ created by the plugin itself, but only permission the “cache” folder.
So I also wonder if there is a problem with that, given the fact that all the folders created by the plugin inside the cache folder already have the permissions to 755.
Simplifying
Folder named ‘cache’ set to 755 – plugin does not clear the cache (when I do the cleaning I change to 777, and then I return to 755).
In my case it is not necessary to make changes to anything else, for that reason all the files and folders automatically generated by the plugin, and they are inside the folder named ‘cache’ are properly configured with the permission 755.
