friendly URLs problem

Hy!

I use your excelelnt plugin (1.3.3). I try to optimize my website, and i find some problems:
“Remove query strings from static resources”

I read, the problem is whit the “?” characters in the filename. I tried to go your plugin’s Advanced Options, and thicked the “Enable friendly Minify urls” function.

After I went to General Options and flushed all caches. And my site crashed (it looks like, the css files are missing).

Do you know, what cause this problem?

I use W3TC plugin too, and in the Browser cache, the “Prevent caching of objects after settings change ” function is disabled.

Thanks
