After 2 days of searching and trying everything available out here and in other forums, have to post this request!
I am trying to integration TL 1.9 Prague with Mantis 1.1.8 without success. What I have done so far:
1. Enabled anonymous_login in Mantis config_inc.php
2. Configured Testlink's /cfg/mantis.cfg.php & custom_config.inc.php
3. Restarted Apache
and nothing.
I had previously integrated Testlink 1.8 with Mantis in another installation without any problems. Dunno why TL 1.9 is giving me so much headache.
Any help would be greatly appreciated!

P.S: I cant use XAMPP since this is an ongoing project and other security aspects.
