[Posted on wordpress.org – didn't know that this forum existed!]
After upgrade, the plugin fails to load/display in the backend Dashboard admin menu….and I cannot locate where to edit the menu order. I even tried the Admin Menu Editor plugin, but this plugin didn't show up as activated (but it has been).
I edited the admin.php file and changed the value from 50 to 7 – but that didn't work, so I give up.
I'm assuming that the admin menu position [of WP Project Manager] conflicts with another plugin. Please point me toward the correct file, change its value, and see it again. 😉
