    I have this annoying problem for which I couldn't find any solution. When I activate the plugin, I get an HTTP 500 Internal Server Error on my site. With the plugin deactivated there is no problem, only when it is active.

    Here is what error messages I got:
    W3 Total Cache error: It appears Page Cache URL rewriting is not working. Please verify that the server configuration allows .htaccess
    Unfortunately disk enhanced page caching will not function without custom rewrite rules. Please ask your server administrator for assistance. Also refer to the install page for the rules for your server.

    Technical info
    .htaccess file contains rules to rewrite url http://www.csirmazandras.hu/w3tc_rewrite_test into http://www.csirmazandras.hu/?w3tc_rewrite_test which, if handled by plugin, return "OK" message.
    The plugin made a request to http://www.csirmazandras.hu/w3tc_rewrite_test but received:
    Resolving host timed out: http://www.csirmazandras.hu
    instead of "OK" response.

    Set the permissions of wp-content/ back to 755, e.g.:
    # chmod 755 /var/www/vhosts/domain.com/httpdocs/wp-content/

    I don't really understand what they mean, so any help is much appreciated!
    Thank your for your time in advance!

    What this means is that the plugin can't find your .htaccess file. This is usually in the root of your WordPress install and is needed by Word Press to create nice URL links.

    Just log into your Terminal App (I have no idea what this is called on a PC) and create the file. Make sure to give is proper read and write permissions for your web server.
