Payment Package Settings Not Getting Saved

Hello,

I have just purchased the developer license of ClassiCraft WP Theme and trying to configure it. I have come across one problem on which I am trying to work from past 4-5 hours but no matter what I do this problem doesnt go away.

From Admin Side > Theme Settings > Advanced Settings I am trying to enter and save the data in "Free Payment Package", "Paid Payment Package and "Recurring Payment Package" and save the settings.... The settings are NOT GETTING SAVED at all..

When I come back to these sections I see all the fields are blank and also on the user side, I dont see any packages and user is able to post the Ad. without selecting any packages (as no packages are visible to him).

I spent 4-5 hours on trying to make this work but now matter what I do, these settings are not getting saved at all.

See this screenshot http://prntscr.com/h30g0i

Please let me know the solution.

Thanks
