Hello @mickysoft,
The issue appears to be caused by the optimization layer of our plugin related to the JavaScript files. I would recommend reactivating the plugin and disabling the FrontEnd optimizations named Minify JavaScript Files and Combine JavaScript Files. If the issue is resolved that way, you can exclude the problematic scripts by defining their handlers into filters placed into the theme’s functions.php file. Then, you can reactivate the mentioned features and the issue should be resolved. You can pass this information to your developer and for more information on how to create the required filters, the following procedure could be used:
The complete set of possible filters can be found in the plugin’s Readme file or directly in the info page here.
The filters related to those features are:
sgo_js_minify_exclude
sgo_javascript_combine_exclude
sgo_javascript_combine_excluded_external_paths
If the issue is not resolved that way, you can open a new ticket on our end and we will be glad to investigate the issue further.
Regards,
Dimitar
