Hi Ed,
I had sent in troubleshooting request to my host, and they have replied that based on their findings, they have identified that this is an application-related issue. They will try to troubleshoot but not able to offer a guaranteed resolution of such application issues.
Should I change to use another slider instead? I have smart slider plugin maybe I can substitute it for now ( I hope it doesn’t conflict with your theme)
Or I will still need to reinstall the Swift Framework again to avoid error in future?
Anyway, I’m very grateful and appreciate all your help so far.
