Error: Menu Data Not Found (50)

Symptom:

When loading a menu the error code "Menu Data Not Found (50)." Appears.

Resolution:

1) Network latency issues: This could be due to the network timing out - as a result the menu may not load

2) Broken image or font: One of the resources required for this menu was unable to load and thus causing this error. Typical files that lead to this issue:

a) Font files - either the incorrect link was used, the font file is unsupported by the kiosk, or the font repository (Google) 

b) Image files - incorrect link was used, or the file type is unsupported by the kiosk (such as .SVG / Vector images)
