mediawiki software installation issue

[#1]

Hi.  I'm having issues with installing the media-wiki software in my ccgi space.  I'm following the instructions at http://www.mediawiki.org/wiki/Manual:Downloading_MediaWiki although also referencing http://community.plus.net/forum/index.php/topic,45441.msg388708.html#msg388708
So I've run chmod 750 config, skipped the database creation and gone to my config page to be told that:

Execution of (index.php) is not permitted for the following reason: Script is not executable. Issue 'chmod 755 filename'

So I'm stumped.  Do plusnet have PHP version 5.0 or later?  Would that be the issue? Sorry of this is something really obvious.

The ccgi server does not support PHP5.
You need to telnet to ccgi.plus.net and login to the command shell and run fixphpperms.sh -r to set the correct permissions on php files.

Thank you Peter, that's got me through that step. What does that command do and did I miss being told to do it somewhere, if you don't mind me asking?

Ah, I need to install the version that works on php 4.  Whoops.

The script just recursively (the -r parameter) finds all .php files and changes their file permissions to be correct for running on plusNets secure ccgi webservers.
It is explained in the help & support pages for CCGI here

Ah, thank you.
