A Plugin broke my site & cant get into admin

Hi,
A plugin I installed broke my website & now I cant get into admin.

-I have been into the ftp and deleted the plugin and that didn’t work.
-I then added a 1 on the end of all plugins to disable all via ftp and that didnt work.
-I went into the database and did a query to diable all plugins
UPDATE wp_options SET option_value = ‘a:0:{}’ WHERE option_name = ‘active_plugins’
that didnt work.
-I tried renaming the index.php file in the plugins folder to index.html, that didnt work.
-I dont want to disable theme and use default,as last time I did that I lost all my widgets & uber menu.
