Getting this Error curl_exec: Protocol "https" not supported or disabled in libcurl. Hostname requested was: plugins.piwik.org

Hello,

I cannot seem to access the Marketplace, I always recieve this error "curl_exec: Protocol “https” not supported or disabled in libcurl. Hostname requested was: plugins.piwik.org"
I have also downloaded the plugin “Custom Dimensions”, it has been activated but whenever I click on it, nothing shows up and I am left with just an blank piwik page.
If someone could please help me with this.
Thanks

Hi,

the error is pretty much what is printed:

curl_exec: Protocol "https" not supported or disabled in libcurl. Hostname requested was: plugins.piwik.org

Piwik tries to download a file from https://plugins.piwik.org and uses curl for this. But the version of curl you have installed either was compiled without support for HTTPS.

See also this FAQ entry of curl:
https://curl.haxx.se/docs/faq.html#Protocol_xxx_not_supported_or_di

Maybe Piwik could fallback to http, but in security terms this would be a pretty bad idea (everyone could intercept and modify the plugin you are downloading).

For this issue please try to run the core:update command on the command line as explained in: https://piwik.org/docs/update/#database-upgrade-for-high-traffic-piwik-servers
