The same site works perfectly on chrome, but all extensions looks like to be disabled. I had run into same errors before.

aleveltech is this a new issue with an existing website? Did you just update Flarum? Or did you just update some extensions? Did it work fine before?

You appear to have a lot of additional scripts on that page, and the syntax of the HTML document itself is broken (you have a second set of HTML doctype, head and body inside of the page body, I think you might have inserted that as part of the custom header).

clarkwinkelmann I believe I this issue is related to text formatter requirement in core. I know there was an error we ran into during the initial upgrade that got fixed. If that dependency didn't get updated for some reason that might be it? Also php flarum cache:clear might help.
