Couldn’t update collection Unable to update category

I had a nice breadcrumb navigation with numerous categories working well. Deleted the categories to rework them. I added a couple new categories and now I can't enable them. Under each category the enable toggle is disabled. when I try to save anything I get the error "Couldn’t update collection Unable to update category".

any clue what is going on?

In case someone runs into this they didn't really explain what happened and had me start a new store. After that I had to move all products from the old to new and delete the old store.

Hi there, I'm getting the same error. When I try to tick "Filter Visibility" and save, I get the following error message. Can someone help please? Thanks!

I'm getting a similar error on a blog when trying to edit its settings. I submitted a ticket to support, so we'll see what they have to say...

Well, I got the standard "we can't help with this" message from support. Looks like they have no idea how to repair a damaged blog collection:

It looks like the CSS may be what is causing the issue. We do not offer support for custom code as it is outside our scope of support, however, we do have resources you can refer to with coding questions and issues.

Has anyone had any luck with this?  

I didn't edit anything on my site (other than leave it for a few months) and the Universal Filter is on my shop, however I get this error when I try to edit the code.

"Couldn’t update collection Unable to update category"

This is not Filter or any other plugin question it's a Squarespace issue, so you need contact their support. I've seen this on client sites and it disappeared one day without any changes

Experiencing this when attempting to update page header code injection in products page.

*Update* Although I get this message, and the option out is to 'discard my changes', those changes ARE showing up when I re-enter the settings/options, even though I was forced to discard. For ex- changes to SEO Description or Code Injection. If it doesn't work after changing one factor, try making your main change, then making some other insignificant change, then backing out via "discard".

Does starting a new store help resolve this issue?
