I had the same problem with an upgrade from 1.1.8 to 1.2. Found that my directory path in apache config was pointing at the top directory instead of the home directory:

old path: /var/www/html/mantis-installs
corrected path: /var/www/html/mantis-installs/mantis-1.2

When I did this, I was able to run the mantis-1.2 install without the root path problem.

Check whether this is your problem
http://www.mantisbt.org/bugs/view.php?id=11534

If yes, have a look at this note for a workaround

Nope, that was not my problem - I checked that after the upgrade as well. Did a full scale egrep for the "bt-1.2" prefix throughout the code and could not find any instances of it.

The soft link doesn't seem to bother it as much as the FILE returned out of the apache confguration. It looks as if your URL detection code is looking for "<something>/mantis" and is only culling that portion out of the URL instead of looking at the full path, e.g. "<someting>/mantisbt-1.2". That's all useless speculation though.

Also, I am on Centos 4 with apache and mysql 5.

Thank you for the answer. I checked, ISS correctly points to directory (C:\Mantis\mantisbt-1.2.0)

I tried to specify path to older mantis (C:\Mantis\mantisbt-1.1.8) - everything rendered well (login page)

I tried to make config_inc.php be equal in both directories (for 1.1.8 and 1.2.0) - problem still exists

So 1.2.0 and 1.1.8 renders root path different way with same config file

See 0010652

Thank you for all responses

Simpliest solution for me is move bugtracker to subfolder

Now I'm using http://bt.example.com/bt/index.php instead of buggy http://bt.example.com/index.php

Anyway fix should be implemented for this problem soon or later
