Can you believe it!
Update. So, meanwhile, I’ve been doing a little research. When the menu blew up the other day, it left a trail of red error codes in the menu dashboard stating, “The given object ID is not that of a menu item“. It seems that WordPress has a built-in limitation. You can’t really put more than 40 menu items on a WordPress menu … not for long, anyway. Because the menu can blow up and disintegrate at any time. This limitation is apparently designed into WordPress. Which, I think you will agree, is totally insane.
So, before I spend time completely reviewing the whole top menu, and reconstructing the 30 or so missing item tabs that WordPress just decided to turf, I am looking into the possibility of a plugin to stabilize the menu. Please bear with me.
Update #2. Okay, folks. I think I may have found something. The Max Mega Menu plugin site explains why the number of menu items is limited in wordpress, and suggests a way to increase the number of menu items. It’s nearly my beddy-bye time, so I’m gonna park this how-to link here, and work on it tomorrow. Wish me luck.
