Help with date format for "first post" hack?
 

Gone

As far as I know, the today/yesterday thing is handled in the vbmail() function.

Why it doesn't work I'm not sure though...

You have change the calls to the vbdate function to enable "yesterday" and "today". For example, the hack contains the function call:

$thread_dateline = vbdate($vboptions['dateformat'], $thread['dateline']);

which, if changed to the following, should work for you:

$thread_dateline = vbdate($vboptions['dateformat'], $thread['dateline'], true);
