JS Error

Hi,

Since version 3.1.4 I have a problem with the plugin and I keep getting JS errors like this:

jquery-migrate.min.js?ver=3.3.2:2 JQMIGRATE: Migrate is installed, version 3.3.2
(index):380 Uncaught TypeError: $ is not a function
at (index):380
member-directory.min.js?ver=3.1.6:1 Uncaught TypeError: e(…).select2 is not a function
at HTMLDocument.<anonymous> (member-directory.min.js?ver=3.1.6:1)
at j (jquery.min.js:2)
at Object.fireWith [as resolveWith] (jquery.min.js:2)
at Function.ready (jquery.min.js:2)
at HTMLDocument.I (jquery.min.js:2)

I updated to 3.1.6 and still no changes.
Do you have a solution?

WP ver. 5.7.2
