Hi,

this is the typical javascript error which you get, if you includes a jquery library in a not Joomla! conform way, while another extension, like Visforms uses the Joomla! conform way and then tries to use this jQuery object.. Mostly it is either the template iteself or another thirdparty extension, which you have installed on your website, that causes the problem.

If you check further you will certainly find that jquery is included on your website twice. One time with a link
Code:
<script src="/media/jui/js/jquery.min.js"></script>
which would be the Joomla! conform way and a second time with a link that might look something like that
Code:
<script src="/modules/mod_evo_frontpage_pro/library/jquery-1.8.3.min.js"></script>
which is not compatible with Joomla! and will break any Joomla! Core or extension javascript that tries to use jQuery, except of course the one extension, that has included this script.

Please check the following post, maybe it can help you fix the problem.

:idea: I recommend you the new and up-to-date documentation for Joomla 4:
docs.joomla-5.visforms.vi-solutions.de/en/docs/
Most of this also applies retrospectively to Joomla 3.
Please only ask 1 question per topic :-).

:idea: Ich empfehle Dir die neue und aktuelle Dokumentation für Joomla 4:
docs.joomla-5.visforms.vi-solutions.de/docs/
Das meiste gilt rückwirkend auch für Joomla 3.
Bitte immer nur 1 Frage pro Thema stellen :-).
