When I had this problem, my menu was up to 62 items and I solved it by increasing the php.ini variable max_input_vars from 1000 to 2000. My host does not allow me to edit php.ini but the host support tech was happy to do it for me.
good info thanks same issue here too.
I had a lot of products under one heading, and wanted to distribute them over 3 headings, under one parent heading. I didn’t add any products, just moved them. I am only getting one of the three subheading showing up under the parent, although I know they are all there. Can anyone help?
