Can't open designer: "Site migration failed"

I’d appreciate some help here - I’m not able to open the designer, much less edit my site.

Upon clicking “Open Designer”, the designer fails to load and alerts: “Site migration failed. Please refresh your page.” Refreshing triggers the same error.

Logging out/logging in didn’t help.

I didn’t try to migrate anything.

Running latest Chrome Version 113.0.5672.92

@Steven_Liss - I recommend that you open a trouble ticket with the Webflow support team.

I figured it out – running AdBlock breaks Webflow.
I simply had to to turn off AdBlock (which, ironically, I had only activated to test how my site rendered to AdBlock users).

Glad you discovered the source of your problem. Rule #1 is to always use Webflow without browser extensions enabled or use incognito or private mode which by default does that for you.
