Redmine

Hi,

I've installed several redmine instances of version 1.2.1 inside a single apache server below different sub-urls. The purpose of the installation is to try out customizations of redmine in the 'development' install. However, after several customizations and configuration work inside the redmine GUI I've got the following 'internal error' when displaying issues or trying to open new issues:

Rendering /appl/srv/webapps/ekogu-integration/public/500.html (500 Internal Server Error)

I made several small customizations inside the redmine code, so I expected I broke something.

To find out what's going on, I cloned the application and database. With 'cloning' I mean, I made a exact copy of the install directory, purged caches, duplicated the database and run through all the steps necessary to configure and migrate the new installation like I would do with restoring a backup in a new place below a new sub-URI (basically following all the steps in the migration/upgrade guide). But surprisingly the 'clone' does not get the internal error anymore. Strange, because the two instances are absolutely identical, only the session key and database name differ.

Then I installed 1.2.2 from scratch and migrated the data from the broken install into it - and it worked without that error! I repeated all the changes I made to the redmine 1.2.1 version and the error still doesn't show up.

Problem solved? Not so: when I clone the new install to the old place (deleting the old install and db completely) - the error shows up again. Somehow it seems to be locked to the sub-url prefix.

I tried restarting apache and clearing cookies in the browser but the error remains.

I am now a bit out of ideas where the error can be. Did anybody get this? The two installations are identical in every detail. When I dump the DB there is no difference. When I diff the redmine dir, I see only expected differences like logfiles. Any ideas where I can look for information left over from the broken install?

Thanks for any help in advance,
Peter
