ok those notices are ok to ignore.. just turn debug off.
i'm going on a hunch here, but have you updated to 2.2.4 yet?
i'm asking this as the top downloads block uses the XOOPS function 'xoops_substr' which i believe has had a bugfix made to it in the latest update.. this maybe the cause, but again it's just a hunch.. something to do with trimmarker.
you could also try opening modules/wfdownloads/blocks/wfdownloads_top.php
and find on line 45 :
$download['title'] = xoops_substr($download['title'], 0, ($options[2] -1));
and replace with
$download['title'] = substr($download['title'], 0, ($options[2] -1));
but try the update 1st.. i'd say it has something to do with this, but it's just a hunch..
