If you look through the panel, there is a section where you can turn off the plugins one by one (or a bunch at a time)...it's called globally disabling them. There is also an option to do this on a page by page basis which is very helpful if you have a certain page that is having issues and it's due to two plugins having a conflict. This is just one idea. You could have theme issues as well. If this is the case, activating the default WordPress theme will typically tell you this. You have to be careful doing this as the Widgets you have setup can disappear. So if you have configuration intensive widgets, you will want to note all the settings or drag them to the inactive widgets section so you can put them back later. The reason I always try Plugin Organizer is similar to the issue with widget settings, some plugins clear settings when fully deactivated. It sounds like you were able to get to the back end if you could install that plugin?
