It has been reported (and verified) that when using WPML, Plethora Sliders failed to be assigned on the corresponding post’s Media Panel.

This issue has been fixed on version 1.3 but if for some reasons you want stick to an earlier version of our theme, here is a workaround:

Download the zip file, unzip, locate the wpml-config.xml file and upload it to your parent theme root folder (to replace the existing one). Next, disable and, enable WMPL plugin to read the new configuration.

At this point, the issue should be resolved.
