Does anyone know how to fix the error message below?
One or more material sections have errors. Make sure you have at least one and that they all have valid IDs.
When I try to approve an e-mail template this error shows up. Thank you!
"Make sure you have at least one and that they all have valid IDs", I'm pretty sure you should look up for your IDs, you probably repeated some of them.
If not, make sure they all have IDs.
That's all I can do for now, but if you want to upload a screenshot or anything, I'll be looking forward to it.
