Gallery 2 troubleshooting

I am locked out of the admin area of a Gallery 2 installation. No user/password combinations work and none of the troubleshooting steps I have tried are working either. Further, it appears that this application is no longer being developed or supported and its user forums have been archived. Surely there must be a way to fix it, but I have reached a block. Any help is greatly appreciated.

Thanks, Dan

Have you tried this thread:

I stopped using G2 and moved up to G3. Now that it is going away, I am in the process of moving over to Piwigo.

Thanks for your reply. Yes, I did see this suggestion earlier, but my Gallery 2 installation does not include a “setup” folder, so I don’t see that this will help.
