Settings Not Displaying

Hi,

We’ve used Sticky Menu to great success on a previous site, but when we tried to use it on one we’re currently developing, the settings don’t display. The tabs show, but the areas underneath are completely blank. I imagine it may be a plugin conflict, but we have a wide range of plugins already in play and it would be very difficult to isolate the one that’s causing it. Any suggestions would be very much appreciated. Thank you!
