I have just installed W3 Total Cache via ftp (problems with installing from Dashboard) and now all I get is:
Fatal error: Call to undefined function wp_cache_init() in /var/www/kysthospitalet.dk/public_html/bagsiden/wp-includes/load.php on line 409
I have removed the plugin via ftp, but it seems to make no difference.
Somebody advised me to rename the remaining plugins via ftp - but I am afraid of making more problems...
Any idea on what to do?
