Excellent thanks chaps.
I've just pulled down the latest code base and all seems to be working again.
After upgrading to v1.17.0, we noticed that with 2 tabs open: 1 for /admin, the other the forum, we get the session mismatch popup saying:
"It looks like your login session is no longer active, or no longer matches with the server. Please refresh this page."
This happens every time the 2 tabs are open. If only 1 tab either just admin or just forum, we notice the issue doesn't happen.
Please help. Thanks!
Sounds similar to https://github.com/NodeBB/NodeBB/issues/9507.
Can you try commenting out the code mentioned in the issue?
@baris Thanks! That seems to have fixed the issue.
