Hi Martin,
I cannot run Agilo for trac 0,98 on CentOS 5.8 with Trac 12.2 and python 2.4.
The only problem I saw when I installed it was that the database update script returned the following: "Database is up to date, no upgrade necessary."
Now, when I go into Trac, I see the normal Trac, and in the plugins section I see the following:
Looks like simplejson dropped support for python2.4 and there is at least one line the simplejson version you have installed that's incompatible with python2.4.
We have updated our dependencies list so that new Agilo installs will pull the correct version of simplejson on python 2.4 systems.
In your case I would simply delete the version of simplejson you have installed and install 2.0.9.
Please let us know if this works for you!
Cheers
