Since I updated from 2.2.0 to 2.2.2, some plugins report that they are updated as well. When I click update, an error message appears:
"There was an error on the form. Please try again."
Also, when I install 2.2.2 from scratch, and try to install the plugins, I get the same message. Try for instance with GuestUser, or ExhibitBuilder.
I got everything through Github.
I didn't go and dive into the code myself. Hope you can fix it soon.
That error is about the CSRF protection that was added in 2.2.2, it's caused when your request didn't contain the token it was supposed to.
Are you using a custom admin theme? Otherwise, the necessary tokens should be already included via hidden inputs where necessary. We haven't had any other similar reports (and I can't personally reproduce your issue).
Yes we are using a custom admin theme. Should have thought of that I suppose.
I will merge with the newest version of the theme and try again. Thanks.
