I have downloaded the Skillbuilders Modal Page Plugin. I have tried to implement the same but my modal window is not showing correctly. I can see all the fields and scroll bar. I also tried to set the initial height/width settings but no luck.
Go into the setting in the Shared Components for the plug-in and change the theme from custom to a number (1-5). Also, make sure to read this:
After going through the Dan's link and changing the Global Settings of the plug-in (changed Theme Custom to 1) all worked fine. Shared Components -> Components Settings -> Skillbuilders Modal Plugins (v2.2)
Thanks Dan for your great help and point me to the right direction.
