I also was having the language error

EP4 FATAL ERROR: No default language set.

and followed the posts here looking for the fix. The quote below didnt really explain to me how it was done. BUT overwriting the query_factory.php file with the default 1.5.3 file worked. I will just replace it with the SEO one later but Im posting here to perhaps ask how the below method works exactly? Is it an entire extra ZC install or just an extra admin folder? I tried an extra admin folder with default ZC 1.5.3 files but that didnt work for me.

Perhaps the fix can come from within the query_factory.php file ?

Im also running 1.5.3 and USU and EP4.

So I set up an admin area in a separate folder that ties into the current database and EP works fine! Not the greatest solution, I am sure, but the best I know of for now until USU gets updated.
