Warning: xcache_isset() [function.xcache-isset]: xcache.var_size is either 0 or too small to enable var data caching in /home/public_html/foorumi/ips_kernel/classCacheXcache.php on line 95

How do i correct this?

edit: fixed by editing /etc/php5/conf.d/xcache.ini

Do you have xcache installed/what is the value of xcache.var_size?

Check your php.ini (most likely) for the xcache variables.

edit: ignore this, just read you fixed it!
