I have just finished setting up a WP site with W3 TC.
When the plugin is active the wp-admin/index.php page becomes blank.
I have tried enabling/disabling all plugins, and the problem seems to be with this one.
When I put define('WP_DEBUG', TRUE); in wp-config.php, wp-admin/index.php spits out:
Notice: load_plugin_textdomain was called with an argument that is deprecated since version 2.7 with no alternative available. in /domains/www.steenkofoed.dk/www/wp-includes/functions.php on line 3323 Notice: Undefined index: general in /domains/www.steenkofoed.dk/www/wp-content/plugins/mailpress/mp-includes/class/MP_Log.class.php on line 36
Maybe the host is running some old version of PHP, I'm not sure, but is there some way this can be fixed?
I have been Googling for a solution but so far no luck.
