I can edit the FAQ, change Admin Settings and the Customisations - but if I try and edit the Terms of Service I get an error on “403 Forbidden” in a modal dialog, on submission. The only option is to click OK, and then it goes back to the editor.
The errors in the console are all to a /posts API I presume:
Interestingly… I can get it to post successfully, but only if I delete most of the content so it’s just a single paragraph. If I try and create something as long as the original, it won’t submit.
