[Duplicate] Marking forums as read doesn't work

[s3_gunzel]

Per title: Clicking the on/off/offlock image on a forum to mark it as read appears to work, and then on page reload does not work.

Checked on MyBB community site, don't have a forum for me to test it on.

Isn't it an old known issue since exactly last 3 years?

I've not had this issue. Eh, reject it, it exists already.
