I am trying to install Fred on a brand new empty Modx V3.0.1-pl site. When I click on “Download Extras” I get the following message: MODX received a blank response from the provider. Please double check your service URL and make sure the provider is a valid provider.
If I try to select a different provider (modx.cms), I get the same error. Not behind a Proxy, cURL is installed and operational, network, laptop etc. are all fine.
I get the same error, but only on my local WAMP installation. It works fine on the webserver.
In the MODX error log a get the message GuzzleHttp\Exception\RequestException sending GET repository for provider modx.com: cURL error 60: SSL certificate problem: unable to get local issuer certificate...
so I assume it’s because the local server can’t verify the SSL certificate.
I was able to fix it by downloading a certificate bundle from here and setting the openssl.cafile value in the “php.ini” to this bundle-file (similar to this stackoverflow topic).
