On one of my sites I saw a modules folder within the modules folder (sites\all\modules\modules) that contained what looked as the content of the \modules folder located in the root.
I thought I might have copied it by accident once, so I deleted it (Stupid me :-) ). From that moment on some errors started. I thought, well, if it looks like the modules folder, just copy the modules folder back to that location.
That *looked* like a fix. Until someone tried to add content, and now the error appears:
Fatal error: Call to undefined function field_attach_load() in /home/wesignnl/domains/postzorgen.nl/public_html/includes/entity.inc on line 321
I looked within the entity.inc, but on a short glimp I can't see whats wrong there.
What I did next was moving all my drupal files, and placing back a fresh drupal install. In that install, I just placed the settigns-file back in sites/all. And the same error is there again.
As it seems module-related (module folder I deleted...) I disabled all modules from the database (status=0). No fix.
Anyone a clue what I can do to get things up and running again?
