simonb.com: blog > ExpressionEngine Invalid URI

This weblog is (currently) running ExpressionEngine. I just had a bizarre problem: when I went to the home page it was only displaying a message saying “Invalid URI” Sometimes it would load part of the page though without the css. An intermittent problem - the hardest to track down. I searched around the forums and the net for why this could be - found nothing. Nothing changed as far as I know so it was a bit odd. There was also nothing obviously wrong in the logs. I fixed it by restarting Apache and MySQL - maybe only one of those needed to be restarted in retrospect. I suspect a bit of PHP had gone wrong somewhere.

Update: Well it turns out that a simple restart was not the solution to the problem. EE’s “Invalid URI” response is not very helpful so I modified the php code to printout the actual URI. This is where it gets weird. Yes I recognised part of the URI but it was from a different virtual server which is using mod_python not mod_php and using Postgresql not MySQL. There seems to be a wondering pointer causing mod_php|python to overwrite eachother. I installed the newest Gentoo versions of Apache and restarted postgresql - it seems OK now…
