So I can see our site here: https://garrysun.com/
I just tried to update and it didn't work so I reverted back to the old version that I had. When I did this I got the site and was able to login and navigate the admin area (I may have been logged in already).
Now when I went back I only get a blank screen: https://garrysun.com/admin/
I think what happened was I changed something in the site settings and click save and it kicked me out and went blank. It was just an email in the Mail setting. I am using version 1.5.4 of OC.
Please help! I need access to this site as soon as possible.
