Hi e.ibrahim.ammar, It would be better if you could provide us the name of the Theme you are using. WCMp Frontend Manager does work on some themes of ThemeForest, to know about them please check http://wc-marketplace.com/third-party-themes/ .
Please visit Frontend Manager to know about the product and the cost.
Also, If you face any problem with the theme and WCMp Frontend Manager, let us know. We would fix that.
