Andrew, I’ve had the same issue with the tinymce-advanced plugin because my hosting service has done the same thing with the PHP setting.
My PHP setting is 5.4 here and I get the same error from it. If there is a way to correct this in the WP dashboard in the editing error, how I do this? The plugin is currently deactivated because of this issue. Could you or someone please tell me how to fix this issue? Because the hosting provider PHP setting in the server is PHP 5.4 and that is what is causing the issue as previously mentioned above and in the previous post to this thread. Please respond soon. P.S If you did fix this problem, how did you do it as I would like to know? Please fill me in tell me if there is anything I need to do from my end.
