Currently receiving this error when trying to edit a post. We have clean and rebuilt along with reimplemented popforums. Currently on .net7 with popforums 19.

Please advise.

Well, as the exception says, the method is missing, which implies that your build isn't shipping the relevant assembly.

So, I had installed the PopForums.Mvc 19.0.1 Nuget package. I downgraded to 19.0.0 and it fixed the issue. Thanks.
