thank you for your quick reply! i cleared browser cache one more and accessed the site via a fresh browser as well, but that does not make any changes :/
i am not sure if it may have something to do with woocommerce installed and enabled in this site. because i find this line:
<link rel='stylesheet' id='select2-css' href='https://www.rinnhofer.info/wp2018/wp-content/plugins/advanced-custom-fields-pro/assets/inc/select2/4/select2.min.css?falkeTS=61277bd691e4f2021' media='all' />
which seems fine.
but i can not find a line with select2-js pointing to a js-file inside acf.
but i can find a line:
<script src='https://www.rinnhofer.info/wp2018/wp-content/plugins/woocommerce/assets/js/select2/select2.full.min.js?falkeTS=61277bd691e4f2021' id='select2-js'></script> which may be have the same file-handle and use a different version inside woocommerce?
