Hello,
the 25-character “eb5f35313da222b04a2be0d2″ string is not added by the Simple Custom CSS & JS plugin. In fact, all the <script type=”text/javascript”> tags on the linked website have such a random 25-character string attached to them. You can deactivate the Simple Custom CSS & JS plugin to see that the random strings are still there attached to all the other <script> tags.
The random string comes from somewhere else, presumably another plugin or it could be added by the CloudFlare service. You can try deactivating one by one the plugins on the website and check the page’s HTML. Also try deactivating the CloudFlare service and see if that changes anything.
