For me everything is ok, It works … No have errors …
This is the solution:
1 – Find topic-tags.php
file, in your template folder.
2 – In topic-tags.php file, find this line:
<?php tag_form(); ?>
3 – Above this line, add the following code:
<?php if ( !bb_current_user_can( 'manage_tags' ) ) {return false;} ?>
I hope it is not wrong, I made this change for me and now works …
[EDIT by chrishajer – there is no bbcode here]
