I run an update from 7.5.6p2 to 7.6.2 on a site witch contains 3 language packs. The update scripts comes to 'update language files automaticly' I say go on and it doesnt come back, the frame stay blank. I try it sometimes but no success. In another run I have to click to change my files manually to go on.
I take a deeper look and found a problem that maybe forced this problem:
/language/admin/dogroupmanage.php missing php in the first line
In one of my own language files was a closing ?> missing at the end. I fixed it and hope the update to 7.7 runs smooth.
