Have you any suggestion how to proceed? Thank you March 28, 2020 at 4:10 pm #1213514 TomLead Developer Lead Developer Hi there, This is likely being caused by a caching/minifying plugin, which is taking the jQuery file and moving it to the footer of your website. jQuery should be excluded from those plugins so it remains at the top of your HTML.

Make sure to use our suggested settings here: https://generatepress.com/fastest-wordpress-theme/ March 30, 2020 at 12:42 pm #1219998 Bernhard I have deleted Autoptimize and re-installed. Now it works without problems. Strange.
