Hi @lkdsacc,
Thank you for the review, but you should understand that this problem comes from your theme. wpForo is used by dozens of thousands website without any issue.
I suppose your theme has JS errors or your theme footer.php
file doesn’t have <?php wp_footer(); ?>
function so the TinyMCE editor JS functions are not loaded on your forum. Please leave your website URL, we can fix it very easy. This problem of your theme will cause issues with other plugins too. You’ll have lots of problems with other plugins too until you don’t fix your theme issue. We can help you detect and resolve it, just let us check it.
Thank you!
