Time and scheduled tasks are not working

[abdobasha2004]

I found
<!-- Do not remove $cronimage or your scheduled tasks will cease to function -->
$cronimage
<!-- Do not remove $cronimage or your scheduled tasks will cease to function -->

was removed becuase I changes copyright notice to an image

when I added $cronimage to footer the whole forum did not appear
just blank page

--------------- Added [DATE]1236610395[/DATE] at [TIME]1236610395[/TIME] ---------------

I removed $cronimage to make the copyright an image
so it is a mistake
when I put back $cronimage to footer
the whole forum does not appear at all
