Mark forums read

[Tyrope]

On the forum index there's a link "Mark Forums Read", just under the statistics block.

Everytime I click it, I get an vBulletin message saying:

If this occurred unexpectedly, please inform the administrator and describe the action you performed before you received this error.

So hereby informing the administrator(s) and describing the actions I performed.
