Dev Troubleshooting

Is your system updated?
Make sure that your system is updated. Dreamwidth code is best supported by Ubuntu Intrepid. To update all your packages, you should be logged in as root and then run:

apt-get update apt-get upgrade

If you need to upgrade Ubuntu from Hardy to Intrepid, first you will want to edit this file:

vi /etc/apt/sources.list

And replace all instances of "hardy" with "intrepid". The easy vi command for that is:

%s/hardy/intrepid/g

Then, run the two  commands above.

Apache Error Logs
The error logs for Apache (the web server) are probably located at:

/var/log/apache2/error.log

Loading blank pages are probably the result of mod_perl crashing (often called a "segfault").
