OK, have run 3 scans and all is clear. Laptop is Windows 7 Ultimate, iPad is iOS 9.something, and now I have also tried my Mac laptop running OS 10 Snow Leopard. I can login with every browser except Firefox. Firefox has not been updated in the last few days, and it was logged in before I cleared the cookies as was recommended to view the Adventurer's Stone page. After that, I could not login on the laptop. I had never tried to login on the iPad before. I have logged in on the Mac Laptop before, but quite a while ago. Cannot log in on the Mac now, and nothing was changed or updated before I tried. Safari, Chrome, and IE will allow a login. Firefox seems to be the bug in the ointment. I have no idea when I had logged in previously in Firefox because the site was set to remember me. That changed when I cleared the cookies.
EDIT: WOOT!!! Was just able to login with Firefox! This edit was entered using Firefox. No idea what changed/was fixed, but I like it! Still can't access Adventurer's page however... Edited, Jun 11th 2017 7:43pm by KC13
