Find the following section of the file:
<!-- bof Down loads ON -->
<tr class="attributeBoxContent">
<td class="pageHeading">
<table border='0' width="100%">
<tr><td class="attributeBoxContent"><table border="0" cellpadding="4" cellspacing="2">
<tr><td class="attributeBoxContent"><table border="0" cellpadding="4" cellspacing="2">
<tr class="attributeBoxContent">
<td class="attributeBoxContent" valign="top"><?php echo TABLE_HEADING_DOWNLOAD; ?> </td>
<td class="attributeBoxContent"><?php echo TABLE_TEXT_FILENAME . '<br />' . zen_draw_input_field('products_attributes_filename', $products_attributes_filename, zen_set_field_length(TABLE_PRODUCTS_ATTRIBUTES_DOWNLOAD, 'products_attributes_filename', 35)); ?> </td>
<td class="attributeBoxContent"><?php echo TABLE_TEXT_MAX_DAYS . '<br />' . zen_draw_input_field('products_attributes_maxdays', $products_attributes_maxdays, 'size="5"'); ?> </td>
<td class="attributeBoxContent"><?php echo TABLE_TEXT_MAX_COUNT . '<br />' . zen_draw_input_field('products_attributes_maxcount', $products_attributes_maxcount, 'size="5"'); ?> </td>
</tr>
</table></td></tr>
</table></td></tr>
</table>
</td>
</tr>
<!-- eof Downloads ON -->
And compare it to what I posted above. They should be identical.
<td class="attributeBoxContent" valign="top"><?php echo TABLE_HEADING_DOWNLOAD; ?> </td>
is the line that I am showing as being at 2002. "Unexpected End" usually occurs when there is a semi-colon or closing bracket missing or something along those lines.
All I can suggest is doing an eyeballs on comparison of the section of the file where it reports the error happening and the same section on the copy of the file that works (download them both from the servers -- and then compare the two -- don't just look at your source file).
There has to be some sort of difference somewhere.
Also, since this section of code is using some of the constants that are setup in one of the language files, you might want to find where they are being set up and making sure that they are not missing their closing semi-colons and such as well. You can find them in admin/languages/english/attributes_controller.php
It is possible that perhaps the error is coming from that file maybe.
