Hi,
I have a fresh new installation of bolt 3.0.3.
I need to install some extensions but when I go the the extend page, I got this error:
Unexpected token < in JSON at position 0
I am able to search extension in the Install a new Extension input.
I am not able to install anything due to this error (I think after removing this error install extension will work)
See my console:

And locally (not on my web server of godaddy) I got this error when go to extend page:
Testing connection to extension server failed: cURL error 60: SSL certificate problem: unable to get local issuer certificate (see http://curl.haxx.se/libcurl/c/libcurl-errors.html)
I read this topic but I don't have the folder pki on my mac.
I just put the cacert.pem in the root on my folder AMPPS in the folder /Applications and I set in my php.ini file in ampps like this:
curl.cainfo = /Applications/AMPPS/extra/etc/openssl/cacert.pem
Thanks everyone! 🙂
