Error with Main Nav Menu

Hi,

I’m getting this error (error-1.jpg) reoccuring. I can resolve it temporarily if I go to Products – Categories and ensure that there are no images assigned for Image for the category page title, Image for categories navigation, and Image for header menu. This will resolve the issue for a short time.

Then, after some time (sometimes days, sometimes hours), those images are assigned in the (Solid) category and the issue arises again.

Over the past 3-4 months this issue has occurred upwards of 10 times. Please assist in the complete resolution.

Also, EVERY plugin has already been disabled and the issue still remains, so please don’t waste time by asking me to do so; it’s already been done.
