Preview not working with BBCodePlus 2.1.17

Created by: steefzz

Hello bkraul,

I recently update the plugin to 2.1.17 (running on Mantis 2.24.1 with php 7.2.31) However, i noticed that the preview button (green check mark) doesn't show a preview anymore.

When i click the button, nothing happens.

Tried with Chrome and Edge (also cleared cache) I don't see anything happening in apache2 error log when clicking it.

Anything else i can do?

Thanks in advance.

Stefan
