The web server seems to be misconfigured. There are two possible ways to fix this:
- You can activate the license on https://hub.getkirby.com/. This will generate a license file that you can then manually place in the
site/configdirectory. - You can set the
remote.caoption toRemote::CA_INTERNALto circumvent the server misconfiguration.
The second option is recommended because it will also enable the update check feature. It would be even better if your hosting provider would fix access to the CA bundle that they themselves have configured in php.ini. But if that’s not possible, the described second solution can be the second-best fix for the request issue.
