MT was working fine on this particular site for the past few months, but a few days ago, this started happening:
Nothing I set in MT saves.
Uncaught TypeError: Cannot read property ‘disabled’ of undefined (line 1)

Something’s wrong

My host is Siteground, and I’ve tried disabling SG Optimizer altogether, per some of your other forum posts, but that didn’t help. This site has had SG Optimizer enabled all along, though, and there was not problem until a few days ago like I said.
I’m not sure what’s happening, but this has caused me a lot of frustration in my work flow. I’m having to manually code the css now. I’ve have MT for over 5 years now. I know the great Sebastian will be able to fix it!
The site has a password on it that I can’t make public. So how can I send you that pw privately? I just sent it to you in a contact form. Let me know if I need to send it a different way.
P.S. If you go to General > Preferences > (bottom right) Regenerate all CSS (can fix certain issues) that mix fix your issue. But it would be great to take a look at your site first before you do that (if at all possible) so I can ensure this bug doesn’t crop up again.
Sebastian, actually, I see that you pushed an update out for MT. I did the update and the problem went away. Everything appears to working normally now. If I see any further issues, I’ll let you know.
What do you think the issue may have been, since the recent update fixed it?
Ah OK, when you upgrade the Regenerate all CSS option I mentioned always runs. It’s primary purpose is to ensure all the data is formatted correctly on each upgrade. But I’ve made it available in the preferences as it can sometimes fix issues that occur when e.g. a save request doesn’t complete properly. Or something else goes wrong.
I suspect the data formatting issue that caused your error was corrected, but it’s impossible to say what caused it in the first place now. If it happens again, please let me know ASAP and I will jump in and have a look.
