First time i forgot to prune forum cache, but second time, when i installed a fresh forum, i did all ok.
I modified directly host archive. (I checked it three times, it's modified)
I know, i already tried this, but the error remains :S
I searched on all install.php (portal_install) and the line with this error doesn't exist (because i deleted it as you said), i deleted cache, i tried from another PC, and nothing, the error still happens, i think this have no sense.
Yes, i edited all files two times, and i also purged the cache, but error remains :(
I'm using mssql 2000, could be the problem?
Any ideas?
EDIT:
I've made a fresh forum install, with no changes, i only edited portal required files and uploaded portal files. If i go to forum's root, i got this ...
