After adding 50 link items to the website (db : jos_
menu) and many new links to the main menu, the Main Menu panel in the administrator disappears - it tries to load, but does not display.

Twice now, I've created a new website using Joomla 1.0.3 and have been able to duplicate this problem. I first added 6 new sections to Joomla's default, next added ~20 new categories (dispersed throughout the new sections), and then began to revise the Main Menu. I added links to the sections, deleted a few default Joomla links (and deleted them in the trash manager), and then began to add category links to parent sections.

I added a good number of links to the main menu without a hitch. But at a certain point, I added one more link and after clicking "save," the main menu page loaded blank. Nothing but the header gfx and menu for the administrator (see attached image).

I've found a similar thread here:
Unable to add new menu item in Main Menu
and per ahaapaka's comment found a similar error logged on my server:
PHP Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 3840 bytes) in /home/user/website.com/html/administrator/includes/menubar.html.php on line 344, referer: http://www.website.com/administrator/index2.php

But further, using phpMyAdmin to inspect jos_menu, I found that by deleting the last entry in the table I could refresh the main menu panel and it would display and function to spec (of course, until I added a new link and then encountered the same problem). For both new installs, I found I encountered this problem when the quantity of links listed in the jos_menu table was 50 - this includes links that are in other menus than the main menu.

The problem is just with the Main Menu. The topmenu, othermenu, and usermenu still display and work to spec with more than 50 items listed in jos_menu.

I'm yet to try ahaapaka's recommended fix to this problem, but with the what I found out with jos_menu I thought perhaps there is a bigger problem here.

Per other suggestions I've found, I've deleted my cache, and have used Firefox Windows/Mac, Safari, and IE 6 - all to no avail. Any ideas for a fix, or did ahaapaka nail it the first time?

thanks!
