[For 1.8] Thank You/Like System v3.3.3 + MyAlerts support

[searcher]

Finally, I solved it with database synchronization

Little clue:
This unfortunate misfortune would not have happened if my admin-cp had been set to English.
When uninstalling the plugin, it says something like,"would you like to drop the entries from database?" That's a clear message. 
The German version only says: "Do you want to uninstall the plugin".

I have two/three other problems.

1. In the plugin settings I have several fields which are not occupied or labeled, see screenshots.

   

2. Although it seems to be set, I don't get any JGrowl notifications, see also screenshot.

3. What value can be set at the bottom?

   

best regards
