Internal Server Error 500 when uploading files via WordPress

Well as the title says I had been getting an internal-server-error-500/ error when uploading files via WordPress. I also had these error in my other non-wordpress sites like my MediaWiki. I use ISPconfig to host everything so I went down a rabbit hole to fix this. I saw several guide / suggestions on the issue and no single guide worked for me so below is a list of the steps I took to fix the issue.

Its worth noting this was a combination of ISPconfig and PHP that was causing the error and thats why most of the single guides to fix it did not work for me.

As normal follow this at your own risk and it helps if you have linux experience to tailor these to fit your system.

1) First under ISPconfig I added the following settings in the custom PHP setting section of each website having issuesdisplay_errors = On

post_max_size = 50M
upload_max_filesize = 50M

2) ssh to your server and edit the php.ini file located in: /etc/php5/cgi

cd /etc/php5/cgi
nano php.ini

change the upload_max_filesize = 2M from 2M to 50M
also change post_max_size = 2M to 50M

exit and save file

3) Last edit fcgid config file

cd /etc/apache2/mods-available/
nano fcgid.conf

add the line MaxRequestLen 52428800

Save and exit

I added this line under FcgidConnectTimeout 20 this is what mine looks like

<IfModule mod_fcgid.c>
FcgidConnectTimeout 20
MaxRequestLen 52428800
<IfModule mod_mime.c>
AddHandler fcgid-script .fcgi
</IfModule>
</IfModule>

4) restart server and wallah you can now upload any image that is 50mb or less!
