Yes i confirm
First of all i would said that i don't know why you ask to 777 chmod wpcontent and wpcontent/plugins, my php configuration don"t allow that to me (security reasons and php5) the highest level i can is 755...
(sorry for my bad english i'm french)
I'm using WP 3.4 and after the plugin installation, i clicked on network activation, but i was redirect to a blank page :
So i came back to my network admin, and i saw that the plugin was not actived over the network : i click on it and actived it.
Ok, so i went to one of my child site and go to the plugin configuration. It told me to add some things into my .htaccess file.
I tried to let the plugin to the the job itself (my htacces was 755 chmod before) but it do not work, so i enter myself those lines into my htacess, ok...
Now i just tried to actived the page cache, i enter the new lines in my htacess, but the plugin said my htaccess said my htacces is not properly configurated... :-(
Ok, so i tried antoher option : minify mode auto
The result was :
Minify is not active. To enable it, add the following rules into the server configuration file (/domains/wp-mastersite.com/public_html/wp-content/w3tc-wp-childsite.com/min/.htaccess) of the site . This can be done automatically, by clicking her
??? This folder simply do not exist !
The only folder that exist is :
>> It appears that W3TCis completly lost... becasu it do not know my child site : wp-childsite.com
Conclusion : I wonder why this plugin has been sais that it works under WP 3.4 and multisite configuration...
