The UDDEIM componant is acting really strange. In the mailbox module, it keeps saying "no new messages: no input file specified" or "new messages: no input file specified" even when there is no new messages. I have set sh404sef to skip the component and it still gives the error. I have tried it with nocache settings and that didn't fix anything :S
What else is strange is that the error doesn't have a specific time when it shows up. It can show up twice in a minute or not show up for like an hour.
It is an SEF issue. With SEF turned onb (tested with both the native joomla sef and with SH404SEF), "index.php?option=com_uddeim&task=ajaxGetNewMessages&no_html=1" loads up no input file error.
