Hello Christian,

There isn't a configuration to turn this off but you can customize the theme file located at /components/com_easydiscuss/themes/wireframe/forums/active.php to remove the ask button. You just need to remove the codes below:

[gist]
<?php if ($activeCategory->canPost()) { ?>
<a class="btn btn-primary ed-forums-cat-header__btn t-lg-pull-right t-xs-mt--lg" href="<?php echo EDR::_('view=ask&category=' . $activeCategory->id);?>">
<i class="fa fa-pencil t-lg-mr--sm"></i> <?php echo JText::_('COM_EASYDISCUSS_NEW_POST');?>
</a>
<?php } ?>
[/gist]

Best regards
Christian

Hi there,

Yes. We recommend you do template override for those changes as it wont be overwrite on your next update. You can follow them here https://stackideas.com/docs/easydiscuss/administrators/templating/template-overrides . Please give it a try and see how it goes.
