I get this message when I log into wordpress:
Fatal error: Class 'WP_User' not found in /home/content/51/8501051/html/blog/wp-includes/pluggable.php on line 33
Blank page except this.
Recently I added a plugin to help with ordering my categories and it happend after I installed the plugin.
I tried to go to plugin folder via FTP and changed the folder name to plugin.hold but still doesn't fix the problem.
Unfortunately I haven't had a chance to backup and I'm afraid I will lose everything I have done so far.
Please help if anyone knows how to fix this.
