After I've installed the JetPack module I saw a lot of plugins I don't need at all but I did not have a deactivate button for them. To make them deactivated, you'll need a bit of database hacking:
To show the active modules list:
SELECT * FROM wp_options WHERE option_name='jetpack_active_modules';The output should be something like this:
+-----------+------------------------+------------------------+----------+
| option_id | option_name | option_value | autoload |
+-----------+------------------------+------------------------+----------+
| 254164 | jetpack_active_modules | a:1:{i:0;s:5:"stats";} | yes |
+-----------+------------------------+------------------------+----------+
1 row in set (0.00 sec)To deactivate ALL the modules ( you will be able to activate one by one after this )
UPDATE wp_options SET option_value='' WHERE option_name='jetpack_active_modules';(Oh, by the way: this entry was written by Peter Molnar, and originally posted on petermolnar dot net.)
