If you have tried to install Vanilla forums ( http://getvanilla.com/ ) on Zymic hosting then you may have noticed you can't get past the installer pages.

To be able to fix this error & get vanilla installed, you will need to edit two files. In this tutorial I will be pointing you to go to "Line 60" or otherwise, and to do this you will need a text editor that has line numbering. A good free version would be Notepad++. Go ahead and download that and use Notepad++ to edit the file as mentioned below.

First you need to open up the file /appg/headers.php and go to line 27.
Line 27 looks like:
CODE
ini_set('session.use_only_cookies', 1);


add an @ symbol to the front of that line so it looks like this:
CODE
@ini_set('session.use_only_cookies', 1);


Now save and upload that file replacing the old version of headers.php.

Next open up /setup/installer.php and go to line 5.
Line 5 looks like:
CODE
ini_set('session.use_only_cookies', 1);


Again we're going to add an @ symbol to the front of the line making it look like:
CODE
@ini_set('session.use_only_cookies', 1);


now in the same installer file, go to line 7.
Line 7 looks like:
CODE
ini_set('track_errors', 1);


and once again add the @ symbol to the front of the line making it look like:
CODE
@ini_set('track_errors', 1);


Go ahead and save that file and upload it replacing the old installer.php.

Now browse to where you've uploaded the vanilla forum and follow the install steps, everything should work properly now!
