How to enable Designer Mode in phpMyAdmin...i am on main server not on local server
I think it requires editing some PMA source files, are you able to do this on your server?
So... i created a db called phpmyadmin, and a user called pma with a random password, and set it in config.inc.php , and 2 lines below started to uncomment from $cfg['Servers'][$i]['pmadb'] to $cfg['Servers'][$i]['userconfig'].
After, i went to libraries/relations.lib.php and searched for $cfgRelation['designerwork'] and set it to true.
Logout and login back to cpanel.
