I'm not very familiar with PHP at all. I have a Wordpress.org blog that I host on Dreamhost, and I downloaded a new WP plugin I wanted to use but it gives me an error saying it only works with PHP5 or higher.
I checked my domain and I'm currently on PHP4. There's a drop down where I can choose from the following version 5 choices:
- PHP5 CGI
- PHP5 FastCGI (recommended)
1) Which one of the above should I pick? (Should I go with the recommended one?)
2) If I upgrade my domain from version 4 to version 5, will this at all break my sites or databases or whatever that use this domain? (ie. my Wordpress blog specifically.) Do I need to do something with my Wordpress blog after I upgrade to a new PHP version to guarantee it'll work?
