Hey @Marc Stridgenthanks for removing my email, wasn't sure if this was public or private. So everything was working perfectly a month ago. Then we had some Malware and used a service called Sucuri and they did a great job. But right after, any time a logged in member (we use Wordpress/Memberpress) would click the "Forums" link from our Dashboard page, it would take them to a login page instead of to our Invision Community. The hosting people and Sucuri people both say it's somebody else.
My first thought was the SSO plugin somehow got messed with, although the API key is correct on the php file. I'm able to login to the Admin Control Panel. Is there anything you can think of that I can do? Do you happen to have a link to the SSO people? Thanks so much!
