In the upload feature in geeklog, which i can no longer access.
What do you mean when you say you can no longer access it? What happens?
Sorry, but I don't have enough information to make an educated guess what happened. I can understand a plugin not working after installation, but I don't see how that should keep you from even going to the plugin admin page (assuming the rest of the site still works).
You could try disabling the plugins
that you tried to install. But that's really only a wild guess.
