Still issues with this, I'm afraid. When using Joomla login, everything works fine, using both
yogahuset.no/joomla-login/ and
yogahuset.no/joomla-login/.
When using SCLogin, I get thrown to a random url within the site, with "Invalid token" message. I've tried deleting cache both on server and browser(s), but the error still persists. Recently, there was a successfull SCLoging, but then again the error was repeated. I'll keep on testing and see if I can find some pattern in this.
