Thread:Project:Support desk/Login required twice: first login reroutes to login page


 * MediaWiki: 1.19.3
 * PHP: 5.2.17
 * MySQL: 5.0.96-log

Hi!

Logging in to my Wiki requires the user to submit the password two times. The first time, the wiki reroutes the user back to the login page without any error message. Only after submitting the login a second time it is recognized and forwarded to the main page. I could replicate this behaviour with different user logins, browsers, and PCs. Logging out and logging in for a third time gets me to the wiki immediately if it happens during the same browser session. So, I suspect it has something to do with cookies. How do I fix this issue?

Thanks in advance! Thomas
