Google Analytics no ending delimiter in Firefox & Edge

Warning: preg_match(): No ending delimiter ‘/’ found in /var/www/omeka-s/modules/GoogleAnalytics/Module.php on line 232

It only shows up in Firefox and Edge for some reason.
The URL is digitalcollections.library.appstate.edu

I run curl on it from other places and look through different browsers.

It looks like someone has already reported this problem to the module’s developers.
