Old ItemIDs being used in notifications

[buf]

Yesterday a user of my forum contacted me because he couldn't reply to a message, or even quote it.
When he sent me the link to the topic I found out the ItemID used was old.

Sometime ago com_smf's ItemID was 35, now it's 37 (don't know why it changed), but it seems some reply notifications are being sent with the old itemid...
Any clues?

Most likely, somebody has the old URL (Itemid=35) bookmarked, and is still using that to access your forum.  This can cause issues for some users, and not for others.

Sometime ago com_smf's ItemID was 35, now it's 37 (don't know why it changed),

The "Itemid" field refers to the Menu id, not the Component id.  So, if you have ever deleted the menu item, or changed it from one menu to another, that number will change to identify the menu items uniquely.

Thanks for the info. I'll ask about this on the Mambo (Joomla?) forum, since I think old itemids should be automatically replaced with the new ones upon access.

Well, they are if people use the navigation links provided, but not if they bookmark specific pages.
