Forum OpenACS Q&A: Broke ETP with multiple installs, how do I dig myself back out?

Icon of envelope Request notifications

Hi all,

The first application I installed into my OpenACS installation was ETP. I couldn't figure out how to use it (maybe it was broken already, I didn't know enough to know what was happening), so I forgot all about it and moved on to other things.

Somewhere along the way I tried to use it again, and installed it again. And this is where the trouble started, though I'm not even sure where to begin to fix it. So I'll just describe what I have:

Five unmounted Edit-This-Page instances under various names and locations (but mostly the default name and location). All of them, when mounted, generate the scary error message copied below when I browse to /edit-this-page, which redirects to etp-setup2. I now understand, from reading the forums and the bug-tracker that ETP has a known, and apparently insurmountable, problem with uninstallation...so my uninstallation attempts have probably broken things further. But, I'd like to make it work, and I have no clue how to go about that. Is there a safe way for me to remove all but one of the instances of ETP and get to a working state? I don't mind poking at the database directly, as long as I have some clue of what I'm supposed to be doing there. Anyone have some pointers for me?

Thanks!

The scariest error message I've yet seen from OACS:

There was a server error processing your request. We apologize.

Here is a detailed dump of what took place at the time of the error, which may assist a programmer in tracking down the problem:
