I have a problem that is probably similar to this one. Some of my modules are not showing for some of the authors in my blog. First it was a problem with the exact same module (publishing module) for one of the other authors, now it's a SEO plugin module for my account.
As a fix i created a ghost account so my authors can write their posts with the main accounts and if there is some module problem they log into this ghost and edit the fields that are missing.
That is not a good solution.
Does anyone know what could be causing it? I've tested in different browsers, different machines and even different OSes, the issue seems to be related to the wordpress user.
Thanks in advance!
