No change after uploading clean version of WP.
So
Renamed personal theme folder and activated 2015 theme.
Disabled all plugins
Working
Enabled all plugins
Working
Activated personal theme with define('WP_DEBUG', true);
several Errors:
Notice: The called constructor method for WP_Widget is deprecated since version 4.3.0! Use
__construct()
Fixed on personal theme but “Publish” button still not working.(ie still have the same problem.
Deactivated all plugins
Still not working
My guess is that it is with my theme. Not a clue why as of yet but if it is, I assume if you have a premium theme then updating it will fix the problem.
