Title: 500 error on installation since version 2.3
ThreadText: # 500 error on installation since version 2.3
  
  (Asked by: username_0 on 2014-12-15)
  
  I have tried everything to install Craft on my server, and I have not been able to do it. I have done this a few times before without any issues, but since version 2.3 was released, I can't access the admin panel to start the installation.
  
  I have followed all the steps in the [documentation](http://buildwithcraft.com/docs/installing), I have created new DB, new domains.... nothing! I get a 500 error every time I want to access the admin area.
  
  What am I missing?

  I had this error, except this solution didn't help. Did some digging and managed to fix using method below:
  
  My setup: CRAFT CMS 3, WINDOWS, MAMP PRO 4.
  
  In your craft folder you can find the error.
  
  craft > storage > logs > web.log
  
  ```
  cURL error 60 SSL certificate problem: unable to get local issuer certificate
  
  ```
  
  Go to <https://curl.haxx.se/docs/caextract.html> and download cacert.pem
  
  Edit MAMP PRO php ini file (file > edit template > php > current version your using
  
  add this to the php.ini file

  ;;;;;;;
  ;CURL
  ;;;;;;;
  curl.cainfo = "x:PATH TO YOUR FILE\WHERE YOU SAVED IT\cacert.pem"

  Has to be an absolute file path.
  
  Save, close and reload your server.
