CMS Made Simple Forums

When trying to open admin page i get this
"You don't have permission to access /admin/ on this server."

I CAN open admin page from different machine and different IP,
so i think my IP is blocked or something.
Im new in CMS so i dont know where i can remove blocked IPs.

I don't think this is related to cmsms. I would check the settings of the webserver (or ask the hosting provider to check).

SOLVED
Yes it was server side problem, my ip (or isp) was blocked, dont know why, but now its working )
