Menu Limit

I don’t know if this is related to evolve or not. In building a website it seemed as though after a certain number of menu items I could add no more. After research and with the help of the service provider I changed the max size of the post to 128M which from articles seem to indicate this should solve the problem. This shows as being active parameters in the PHP.

However I still have the same problem if I had anything else on the menu and try and save the menu anything additional is not saved. We tried deactivating all plug-ins, negative help.

If anyone has any experience or suggestions it would be greatly appreciated. Thank you
