Hi Ian, I am using ubuntu 8.04 and firefox 2 and no firebug because on my ubuntu installation firefox 3 hangs and I am unable to install a version of firebug that is compatible with firefox 2. In the absence of firebug, I looked for the javascript errors in the firefox error log and there were none. I am hoping that when ubuntu 9.04 is released a little later this month, I will be able to start using firefox 3 and firebug. I am working through Jason Kohle's tutorial on a single computer. It's a good tutorial and all of it 'just worked' except for saving changes back to the database. On Fri, Apr 17, 2009 at 12:27 PM, Ian Docherty <catal...@iandocherty.com>wrote:
