We have checked with server details it follow all the required things.
As we have checked with other server every time we face this above fatal error which we have mention.
I already promote this to my client ,but due to this want to move other extension.
Please have a look this.
Also check the screenshot for system information.
I am totally disappoint from you as you are not really willing for this.
For you i have tested on other version as well and send you proper screen-shot and error message.
But You are giving same response instead of looking in this issue
