Finally!
Found the solution, at least it works, however maybe there’s a better way of doing it.
Anyway, increasing the memory limit to 64 resolved all of my issues. “Thank you G”!

Hi!
This is driving me nuts! It should be so simple but I cant get it to work.
Running latest versions of WP and the bbPress plugin, installed within WP.
Then I download the language file (sv_SE, swedish) and pretty much everything in the backend stops working.
Depending on what other plugins I have active at the same time different parts stop working.
I’ve tried to put the file in the location you described and the bbpress/bbp-language folder as well.
Please help me!
