1. i cant see the ajax, i mean if i use 3 letter nothing there show.
2. how to activate the RTL because its not RTL nor in the admin and about the frontend, i cant see it in action because the ajax isnt working.
2. The RTL does not have to be enabled, the plugin will be printed in RTL direction on the front-end automatically. The back-end preview can be different a bit, but the front-end should be in RTL mode automatically.
