Dear Mohammed,
You are right, I accidentally turned off images on the arabic version. I turned them back on, they should start showing after the cache expires.
The safest way is to copy the wp-content/plugins/reladet-posts-pro folder and all of it’s content to the production site. It contains all the modifications I made.
As for the settings, they are stored in the database, but all I did was disabled timthumb (image options->use timthumb): http://i.imgur.com/YudqKLK.png
and also i made a change on the compatibility options panel, swithcing the javascript source to “Non-minified scoped”: http://i.imgur.com/KA51op8.png
If you copy the files from the plugin folder and make sure, that these options are changed, it should work as on the test site.
