Hello @spillinova
Please update to the just released version 1.2.6. I understand that if you are using the admin panel in a small screen – ‘tablet or mobile that you will not be able to see the yellow sidebar on the admin panel after we added this Tweak in Version 1.2.5.6 on the 18th of December 2014.
* Tweak – Yellow sidebar on Pro Version Menus dose not show in Mobile screens to optimize admin panel screen space.
In this new release among other things we have added this tweak
* Tweak – Added description text to the top of each Pro Version yellow border section
You can read the full changelog of this new version here.
The Plugins description explains how the lite and Pro Versions works – you can read that here – but this is the applicable section
Lite & Pro Version Admin Interface
All a3rev Lite Version plugins have exactly the same admin interface as the Pro Version. Pro Version features and settings are easy to spot on the admin dashboard as they are inside of a Yellow border. The Pro Version settings are all active on the admin panels so they can be used BUT the settings do not save when changes are saved and hence are not applied to the front end. Upgrading to the Pro version activates all the Pro version Features and Settings and removes the Yellow side bar and borders.
Hope that helps you a bit.
