After every single time we upgrade our totara environments, our custom site logo shows a red X (missing img type error) and when we try to go to Appearance > Themes > Custom Totara Reponsive.. we get the below error. So we can no longer use the theme or fix the logo. I've opened a trouble ticket a couple times now but they can't seem to replicate the issue. The issue does NOT occur if we go in and switch the theme off of Custom Totara Responsive to something else before doing an upgrade .. Although we found this method to get around the issue, it's some times missed by our system admins when they upgrade the environment.. so it's still an issue i'd like to figure out why it's happening. Does anyone have any clue? This is getting quite annoying!
