The previous post you had on this still seems like it should work:
www.sourcecoast.com/forums/jfbconnect/jf...o-template-s-buttons
Basically, in the /modules/mod_sclogin/tmpl/joomlaLogin_vertical.php file, you'll find the following two blocks:
<button type="submit" name="Submit" class="btn btn-primary <?php if (!$showRegisterLinkInLogin)
and
<a class="btn" href="<?php echo $helper->registerLink; ?>"><?php echo JText::_('MOD_SCLOGIN_REGISTER_FOR_THIS_SITE'); ?></a>Update those so they look like:
<button type="submit" name="Submit" class="art-button <?php if (!$showRegisterLinkInLogin)
and
<a class="art-button" href="<?php echo $helper->registerLink; ?>"><?php echo JText::_('MOD_SCLOGIN_REGISTER_FOR_THIS_SITE'); ?></a>
To note, you can make these changes permanent by using a template override. However, then, you may run into issues if you upgrade by needing to incorporate any HTML changes we make to those files into your override. It's your choice:

I hope that helps, but if not, let us know.
Thanks,
