Menu Admin Page Broken

Hi,

I’m working on a new installation, and the menus were working fine but after posting about 20 test posts the Menu Admin page doesn’t load completely and some of the submenus previously defined do not appear.

Tried changing themes back and forth but that didn’t work.

I’ve seen posts about this that refer to increasing WP memory but that didn’t work.

I’ve also seen other posts about this that point out that the page doesn’t fully load which is true for me but I don’t know how I can fix this.

The code below shows how/when the code ends abruptly on this page.

Any help is appreciated – thanks!
Jeremy
