Redirect issue (cache enabled)

First, try with the System - Cache plugin disabled. That plugin can cause lots of random issues, and is why it's disabled by default on all Joomla installations. The Global Configuration caching setting will still provide some healthy caching benefits.

Once done, clear the Joomla cache and test again.

If that doesn't work, in the SClogin -> Advanced parameters area, there's another setting for Caching.. try disabling that, clearing cache and testing again.

Hopefully, one of those will help get you going. If so, we *may* be able to help you re-enable the caching that was causing problems, but we need to start somewhere.

Thanks,

The invalid token error is an issue with Joomla in general. The System - Cache plugin has an option for "Enable Browser Caching". That setting should not be enabled at all if your site allows logins. Browser caching will prevent pages from updating when a user has logged in.

Either way, I'm glad you got things going. If you need anything else, just let us know.

Finally, if you haven't already, please consider leaving a rating and review for SCLogin, or our support, on the Joomla Extension Directory. It certainly isn't required, but is very appreciated:

Thanks for letting me know about your System - Cache settings. We'll have to look into why the SCLogin module caching had to be disabled. It should have a very minimal impact on performance, if any.

As always, if you need anything else, just let us know.

Thanks,
Alex
