Try to install Enable jQuery Migrate Helper plugin. See if it helps.
Fantastic!! That seems to have fixed my issue.
Thank you very much Jose
I was looking up the support link for Weaver and found this: https://weavertheme.com/why-weaver/
>> PLEASE! DO NOT USE WEAVER II. Weaver II is now obsolete, and will not be getting anything but emergency compatibility updates. SWITCH TO WEAVER XTREME! <<
If the above helper plugin works, please let the weaver folks know.
Because you’re using a commercial theme/plugin, please use their official support channel. We feel they are best equipped to support their products.
Commercial products are not supported in these forums.
Weaver II is definitely way obsolete by now.
Below is the article to convert a weaver II site to Xtreme
