I recently started randomly seeing the following error in a development environment for a PHP application that I am maintaining.
cURL error 77: error setting certificate verify locations: CAfile: c:\<<Path removed>>\cacert.pem CApath: none (see http://curl.haxx.se/libcurl/c/libcurl-errors.html)
What was weird was that the CA file existed at the path that was shown in the error. Restarting Apache seemed to fix the issue for a little bit, but then the issue would come back.
