After some additional testing, I've found the source of the problem to be a 3rd party javascript file that I'm loading in one view/page. If I navigate to this page and then navigate to my crud pages and try to perform an action then I get the error. If I don't navigate to that page, then I don't get the error on the crud pages. Is there a way I can isolate this javascript so that it doesn't affect other pages?
This is very useful, thanks ismcagdas!
Yes, in 5.4 Visual Settings there is now the option to pick from predefined colors. The blue theme looks nice, there's a pink but I wish it was red. Thanks again for your help.
Thanks for the response, I'll try an upgrade first.
