I have few CRM 6.5 instances running and I share a little issue with them.
There are some labels I cannot change no matter what. When I post the changes I get no error but the labels don't change.
I checked the permissions and they seem all ok (755 for directories, 644 for files).
A few modules have their labels in a directory called ext, while the other modules have the languages directory inside the modules directory... outside this ext directory.
Since the error seems to occur more often with modules which have their languages directory inside ext directory... shall I try moving the dir outside? Just wonder if it could be the right solution.
