Do you have any other plugins installed? You can go to Admin CP->Configuration->Settings Then choose disable all plugins. If, after doing this, you can view the index normally, it is a problem with one of your plugins. Look to see if any of them hook to either index_start or index_end. I'm pretty sure it is one of those two hooks that is being used by a plugin.
