500 error on installation since version 2.3

Question

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, 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?

Answer 1

I might be shooting in the sky, but make sure that in your in your .htaccess you have

RewriteBase /

after

RewriteEngine On

Answer 2

In case it helps someone, my issue was the permissions for the root index.php file...It was 666 (writeable by group) and when I switched that file permissions to 644, the installation was able to move forward.

Answer 3

I had the same problems after updates by a provider. The solution was add a setting called overridePhpSessionLocation and set it to auto. https://docs.craftcms.com/v2/config-settings.html#general

Answer 4

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.
