Answer 1

edit just re-read your message. You will need ssh access in order to install WP-CLI, so don't know how helpful this is without it.

I advise you to install WP-CLI, not just for this specific problem, but because it rules. It's a command line interface for Wordpress, meaning you can manage every aspect of your site from your terminal/shell.

In this case all you would need to do is run this command:

wp plugin deactivate <broken-plugin>

Fortunately, installation does not require you to login to the backend at all, so this should work.

Answer 2

If you have access to the MySQL server that's hosting your WordPress installation data, you can get a list of active plugins with the following query:

SELECT * FROM wp_options WHERE option_name = 'active_plugins';

to deactivate all plugins, you can do something along the lines of

UPDATE wp_options SET option_value = 'a:0:{}' WHERE option_name = 'active_plugins';

as I recall.

If you are only wanting to disable one plugin, you can CAREFULLY edit the text for 'active_plugins' and UPDATE accordingly.
