Hi team, I have 2 members who have reported this problem, and one of them is our moderator/admin, so we can't get any answers to forum questions.

They report getting this error once they login and view a random number of forum posts (2-5) successfully and then they get the error on their next forum link click.

They also get it if they try add a topic or a reply. If they login fresh, and try add topic or reply it goes to Internal Server Error. But if they login again fresh, their post or reply has saved.

But as soon as they try click on it, it goes to error (I have copy and pasted the error text from Chrome below).

Because the problem is user based, we think it's perhaps a redirect or cookie based issue (with a looping redirect). But when I login as one of the affected customers I can replicate it on my browser. But as an admin in the forum I don't get the error. So perhaps it's not cookie based??

We checked the logs in Memberium on our site in WP Admin, and it has an error log here but that same error log exists nowhere else on the server.

Have tried changing themes and deactivated all other plugins.

What do you advise?
