Hi Justin,
Yes, I had tried (int)($_GET['id']) as well, just didn't mention it here as my
email
was getting so damn long! ;).
Didn't try intval, will do. And I'll try the other stuff -- but I just mention
that I've seen this working fine in 1.3.4
which makes me confused.
As for tying $e right -- I should hope so!-- If not, I've got more problems
than I know ;)
Will try debug level and let you know.
