Dreamhost
From b2evolution manual
If you decide to run b2evolution on a Dreamhost account, then read this page for some information about making it work as smoothly as possible.
[edit] Extra-path info
Dreamhost allows you to run php in a few different ways.
- PHP 5 as CGI
- PHP 4 as CGI
- PHP 4 as an Apache module
Numbers 1 and 3 work fine, but if you use PHP4 as CGI there are problems with Extra-path info. If you enable that backoffice setting (to make urls look nicer), then the permalink urls won't work. To fix it, just switcht o PHP 5 or disable CGI (if you want to stick with PHP 4). To do that, log into the Dreamhost panel, go to Domains > Manage domains, then click "Edit" next to the domain you want to change. This will display a page that lets you change your settings.
For more info on this issue, see this forum thread.
[edit] allow_url_fopen
Dreamhost does not allow scripts to use fopen() to connect to an external web page. b2evolution doesn't use this, but future plugins may depend on it. Usually, the connection can be written to use cURL instead.
