I’m so sorry to hear you are having issues making updates to your site. It’s definitely no fun when things don’t work the way we expect them to.
I made a copy of your site and imported it for testing and I was able to make changes using the Editor and publish them.
We did have a small issue with the Editor on Monday, but the team pushed out a fix for this and that has been resolved.
There are a few factors which could cause this, your internet connection, ISP (internet service provider) issues, older browser versions, browser extensions, or of course a bug.
(1) Try to reproduce the error while being logged into Webflow using Incognito mode with browser extensions turned off: https://support.google.com/chrome/answer/95464
Or if you are using Safari, in Private mode.
(2) If the problem persists, please take a screenshot of your Console and send it to me: https://cl.ly/1c8d19690210
(3)Could you please let me know what browser version you’re using by sending me your information from this page?
I’ll be standing by to help when you reply!
