Hello everyone!
For a few months I have a problem with login to multiple contexts. This happened on Revolution from 2.5.5, now I got 2.5.7.
I have an context called "acp" for some groups. User is redirected to "acp" context after logged in on /manager/ page. Sometimes it redirects to "acp" context and everything works fine. Sometimes it redirects from "acp" to /manager/ page to login again. So, you can't login, everytime you trying to do it, page redirects to /manager/ login page.
Clearing cookies, sessions - fixes the problem, but only for short time.
It can happen on one machine, but wont happen on another one.
If someone need more information - ask.
Thank you.
