Your problem is NOT that the extension is not enabled (it IS).

Your problem is this:

dlopen(): file not found: /usr/lib/php/extensions/no-debug-non-zts-20160303/

This path and/or file just does not exist. Check the ini for the "extension_dir" folder setting. Locate the proper folder and adjust the "extension_dir" folder setting accordingly.
