2.0rc1: Installation error "Undefined index: HTTPS in..."

I get an Error at the first page of the installation:

> Notice: Undefined index: HTTPS in /Users***/Sites/modx20rc1/setup/index.php on line 44

Line 44: $installBaseUrl .= ($_SERVER[’SERVER_PORT’] == 80 || isset ($_SERVER[’HTTPS’]) || strtolower($_SERVER[’HTTPS’]) == ’on’) ? ’’ : ’:’ . $_SERVER[’SERVER_PORT’];

Seems like this part isn`t correct because the index is not set:

> strtolower($_SERVER[’HTTPS’]) == ’on’)

If I delete this (no HTTPS anyway), setup begins correctly and continues without errors. If I continue with that error I get a "Headers already send"-Message on page 2.

Thanks, to avoid this for now you should be able to set your error_reporting level on your PHP configuration to exclude E_NOTICE warnings.

Just trying to respond to Shaun on JIRA (no server response atm):

Hi Shaun,

this is just the standard MAMP config, I think other users will also run into this issue. So a hint here:

http://svn.modxcms.com/docs/display/revolution/Fresh+Installation#FreshInstallation-MAMPonMacOSX

would be helpful. Problem is, the settings of MAMP are so user friendly, there is no setting for the SERVER global vars ;-)

BTW: It is not only a E_NOTICE problem, the setup breaks on the next page, if you continue in spite of that error.

The documentation has been updated. Thanks for catching this.

So there is no $_SERVER[’HTTPS’] set.
