I have installed W3 Total Caché and the results are very good, better tha Wp-Super Caché, but i have two problems.
First i have noted that the blog is more slow when it have to write things. For examen the process of publish a post or save a draft is more slow since i have the plugin installed.
Another problem that i have is that when i activate minify and the Rewrite URL option y have the same message.
"It appears Minify URL rewriting is not working. If using apache, verify that the server configuration allows .htaccess"
I have seen that the persmisions of the fil are 644 that is good.
Thanks for your help.
