I finally did a shift refresh and it worked. Thank you again.
Thank you both, but I tried everything you suggested with no luck. I have the impression that its a mater of dbase update of the new version did. I don’t know how to check this. Any ideas?
I had the same problem and I deactivated the plugin “pluginstaller” and it worked. My problem started when I upgraded to 2.7 and continued with 2.7.1
Hope it works for you too.
