PLEASE: read this short hints before you write a topic:
Use search forum before you add a new question.
Did you search User or Installation manual before?
Don't use the forum as a Bug Tracker - use http://mantis.testlink.org/login_page.php. Bug issues report done here will be DELETED
Consider that some issues are related to Apache, browser or database instead of TestLink. Use google at first.
