Hi,
I deactivated all the plugins and used the Twenty Seventeen themes, And left the download manager plugin active. Cleared the browser cache, but the problem stayed the same.
Although I disabled all the plugins and themes, still the GoDaddy server uses caching and security software that I subscribed to it. Maybe that security causing the issue, which is not like a plugin, and I can’t disable it. The security is within GoDaddy. Possibly that is not the cause. I am not sure.
Kind regards
Habib
