Hello,

Can anybody help me with this? I put so much work in building the website, I hope I do not have to start all over again.

This is a very common php error, it means you have placed some code before session_start() has been called. This function should always be the first to be called as sessions rely on the unmodified header.

Hi all, Just wondering how to make a classifieds ads website using PHP. I'm thinking it'd be much easier to use CMS such as Joomla to create something complicated like this rather than coding from scratch. The site will have login features, search features, ad listings for selling and buying, ads for personals and cars, send emails to friend features. Does this site look too big? It's smaller than ebay, of course. So do you think it's...

If I wanted to build a website with forums, news feeds, galleries, event calander, document managment, etc. I do so in Joomla easily. But, I would perfer to use django/python, if that would be at all practical. I suppose I could put python scripts into django, if those scripts exist.

WTF is it? like most of these wonder tools, you find the site, and it tells you lots of stuff that you don't need, but the main questions:- what is it? where does it fit on my server? (debian/apache2/php5/mysql) etc. why should I want to use it? go unanswered...;-)

I agreed to write an event registration site for a group and then later found out that their website was created with Joomla. I had never heard of Joomla so I started reading about it and it seems like a great idea for people who don't write code and want a quick, great looking website. However, it is limited to the templates and add-ons that have been written specifically for Joomla. I don't have the time or inclination to learn what I need...
