Hi,
it is because the "Logo" href doesn't have any URL attribute. But it should have linked to the "Joomla Root" (which is the homepage) I am seeing you have made a lot of changes on the template, did you touch the "Template Layout" and maybe accidentally delete the "head"? and define another custom layout in there instead?
anyway, try this:
1- open this PHP file:
templates ▸ flexible_stylemart ▸ tpls ▸ blocks ▸ head.php
and look for this line:
<a href="<?php echo JURI::base(true) ?>" title="<?php echo strip_tags($sitename) ?>" title="<?php echo $slogan ?>">
replace it with this:
<a href="http://luisaloves.com" title="<?php echo strip_tags($sitename) ?>" title="<?php echo $slogan ?>">
and check if the logo is not linked to homepage.
Regards.
