Hi,
My site is a .com hosted by 123reg. I ran ithemes for months with no problem. However, now when it is activated the next time I try to log (via .com/wp-admin) I get the message ‘This has been disabled’. If I then enter the site through WordPress and disable the plugin I can get straight back in. Yesterday I was looking at settings and in file permissions it was suggesting I change the value of wp-config.php and .htaccess from 644 to 444. I wondered if this was the problem and I need to go into my host files and changes these?
