Looks to me like you somehow made edits to the core file rankings.php and dont rank by your default ranking method youve set in admin.
Make a backup of sources/rankings.php and upload a fresh copy of that file to verify if thats the case
Ah i see where the issue is. table_row and table_row_premium are files which are called together with table_open and table_close. So it becomes invalid html.
( as you see table_row.html is a table style layout ) and so is table_row_premium.html
so you basicly have now
table > tr > div > table_close = invalid html
Try to wrap your code in table_row_premium with
<tr><td>
your coding
</td></tr>
and see if it fixes it
