THINK I FIXED IT USING:

WHICH:
WordPress Error: SSL certificate problem, verify that the CA cert is OK
Symptom
In WordPress, when trying to install a Theme, view the RSS or performing other operations that use CURL, the following error message appeared:
SSL certificate problem, verify that the CA cert is OK.
Details: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed
Solution
This is because WordPress is using its own certificate bundle, overriding the global system certificate bundle. The problem is that the certificate bundle that WordPress has is old and needs to be updated. To do this, please download the latest one from https://curl.haxx.se/ca/cacert.pem and save it as ca-bundle.crt
Upload this file to: wp-includes/certificates/ca-bundle.crt
I WILL DO SOMEMORE TESTING!!!
