Hi Tony!
Although your solution didn't work for me, it certainly gave me the right hint, of what is going wrong. This is clearly a bug on the side of the Module.
What i figured out by comparing HTML Codes: When there is no Custom Header or Footer set, the Module formats its entries with a table. The definition of the table must be hardcoded within the module and gets overwritten once you set the header.
On the footer, the same thing happens => the closing HTML-Tags get lost.
So my solution: I copied the HTML code of the working, well formated version into the Custom Header/Footer fields and it worked.
The following code works fine (for me)
In the costum header field, type:
Add your Header-Text here <br>
<table class="mod_events_latest_table jevbootstrap" width="100%" border="0" cellspacing="0" cellpadding="0" align="center">
<tr><td class="mod_events_latest_first" style="border-color:#ccc">
and in the Footer:
</td>
</tr>
</tbody>
</table>
<br>
Add Footer-Text here
I hope that helps at least somebody!
Thanks for the help,
Mares
