Settings for PHP execution - Ubuntu Apache

[tonyg]

I am a newbie. I'm sure this question reveals that. I have been coding in PHP though for a while on Windows so I know a bit about that.

Anyhow, we installed Ubuntu Hoary, and Apache, PHP4,
MySql etc. on a new server.

Everything was great - phptest.php w/ phpinfo() worked fine from a remote browser, yada yada.

Then, on the server, I messed around with sudo chmod, taking away permissions from the world for accessing /var/www, then putting permissions back.

Now if I access the directory through a browser, instead of executing php files, it prompts to download then!!!!

Crap! What the hell did I do??? Help!!!!!

Find in your apache config files where it has:

LoadModule php4_module modules/libphp4.so

make sure that under it you have:

AddType application/x-httpd-php .php

and all make sure you have:

DirectoryIndex index.php

My guess is that you have these in seperate files and that you change the permissions on them so that apache can't read them. find the files and chmod them back so that apache can read them.
