Problem with extensions when installing wampserver 3.1.0 (no replies)

Install version 3.1.3 seems that everything works fine, except that some php extensions give problems, this is the php log when starting the wampserver for the first time.

Apache works well at least at its first start.
I followed the instructions uninstalling the previous version I had, stopping the processes, verifying that I have everything updated and ready to install the wampserver.

I reiterate that everything works fine except this problem of extensions.

What is this error?
How should I solve it?
