FIX: Duplicate Entry in 'sys_localization_key'

Ok so I did an upgrade from 7.0.9 to 7.0.1 (B1 then B2).

But when it came to re-installing some modues it said the was a duplicate entry in 'sys_localization_key'

Here is the code i ran in phpMyAdmin

DELETE FROM `sys_localization_keys` WHERE `Key` =  '_sys_module_blogs';

Just replace blogs with what ever module is giving you the error.

eg:

DELETE FROM `sys_localization_keys` WHERE `Key` =  '_sys_module_ads';
DELETE FROM `sys_localization_keys` WHERE `Key` =  '_sys_module_blogs'; 
DELETE FROM `sys_localization_keys` WHERE `Key` =  '_sys_module_files'; 
DELETE FROM `sys_localization_keys` WHERE `Key` =  '_sys_module_poll'; 
DELETE FROM `sys_localization_keys` WHERE `Key` =  '_sys_module_simple_messenger'; 

Hope this helps fixing issues after updating a little easier 

I had this same problem with simple mensenger.

Simply delete the duplicate key in the database and then install the module through the panel adm.

Hope that helps!

I'll appreciate your help.
