So, lately W3 Total Cache started to say this: It appears Page Cache URL rewriting is not working. If using apache, verify that the server configuration allows .htaccess or if using nginx verify all configuration files are included in the configuration.
The .htaccess directives are where they was supposed to be and are what they was supposed to be (according to install tab). So, after this erro started to happen, i noticed this on my error_log:
[12-Jan-2012 19:21:55] PHP Fatal error: Call to undefined function w3_url_format() in /xxxx/xxxx/xxxxx/wp-content/plugins/w3-total-cache/lib/W3/Plugin/PgCacheAdmin.php on line 213
Over and over again... to a point where i need to delete the error_log lots of times, cause the size starts to bother me.
If i disable Disk (Enhanced) and choose Disk it works again. Is there any fix for that? I reported it was a bug, but never got any reply.
I'm running LiteSpeed, CloudLinux and CloudFlare. On a side note, i also have eAccelerator activated on the server, but W3 Total Cache can't see it?
