Thanks for the response. Uninstalling and reinstalling the plugin did not help. I’ve reached out to our server host, but have not heard back from them yet. We’ve used your plugin on the same webhost before without issues, so I’m not sure it’s being blocked.
I did notice something when doing some additional troubleshooting. There seems to be a double slash in the addresses after “modules”. This may possibly be the cause, though I am unsure what is causing the double slash.
