How do I remove the xoops tag at the bottom of the page?
You need to edit your theme.html file and remove the lines that call the image as follows: (taken from default theme. This may vary)
<table cellspacing="0">
<tr id="footerbar">
<td><a href="https://xoops.org/" target="_blank"><img src="<{$xoops_imageurl}>poweredby.gif" alt="" /></a></td>
</tr>
</table>
