Hi there,
You can achieve this by removing codes below at this path
.../components/com_easydiscuss/themes/wireframe/toolbar/default.php
I would advice you to do template override for it as follow
https://stackideas.com/docs/easydiscuss/administrators/templating/template-overrides
You need to create path as follow ->
template/your_current_template/html/com_easydiscuss/toolbar/default.php
<li class="<?php echo $active == 'forums' ? ' is-active' : '';?>">
<a href="<?php echo EDR::_('view=forums');?>" class="ed-navbar__footer-link"><?php echo JText::_('COM_EASYDISCUSS_TOOLBAR_FORUMS');?></a>
</li>
Please give it a try and see how it goes.
