W3 Total Cache displays weird characters

Hello.
Recently I installed W3 Total Cache plugin, on my Wordpress site with Gamezone theme, to speed up my site and i identified a problem that does not know how to solve.
Once installed the plugin , all good , the speed of the site grew as Google Page Speed ​​Tool.
The problem is that once installed this plugin, my site works only in Chrome normal . In all other browsers , including mobile phone versions are displayed some strange character sets when you visit the site.
I read about this issue on wordpress forum (http://wordpress.stackexchange.com/questions/59309/page-output-in-strange-characters) because it was opened a topic on this subject , I followed many tips but the problem was still not solved.
I disabled gzip compression , i introduced or removed from the file . Htaccess different lines of code.
I mention that at this time the plugin is disabled and the. Htaccess I brought it to its original shape.
Please help me with this problem because I really want to install w3 total cache plugin to speed up the site.

Hi!
I've tried to activate this plugin and didn't get the error. I've tested all the most popular browsers. Probably, some of your plugins are not compatible with each other.
