Menu page not saving correctly.

Hi,

I have a site with a large menu, set up using the WordPress wp_page_menu function.

Up until now, it has all worked fine, however of late it has become increasing slower to use when adding new pages.

It has now finally hit the point where it will not save.

The menu currently contains approximately 90 pages.

After reading a myriad of ideas via Google search, and having tried such things as;

– adding “set_time_limit (120);” to wp-config.php
– removing all lines containing “menu_data[‘description’]” within wp-includes nav-menu.php

I am still getting nowhere.

Any changes I try to make to my menu, when saved, either end up taking me to an “Internal Server Error” or if not, the changes I have made do not save.

It is looking like I am going to have to drop using the wp_page_menu function and do it all manually.

Before doing so, I thought someone on here may know of a solution.

Please advise if you know how to fix this problem.

Thank you
