do cellpadding="0" as stated above
and
FIND:
HTML Code:
<!-- paypal donations end -->
</table>
</td>
<td>
<!-- left side block end -->
REPLACE IT WITH:
HTML Code:
<!-- paypal donations end -->
</table>
</td>
<td> </td>
<td>
<!-- left side block end -->
NOTE: CSS is the best route but the above is the easiest and less problematic for those who do not know CSS/XHTML.
