I am writing a drupal 6, custom module, the page that I am calling in hook_menu is giving me a page not found error or it is displaying empty page without any content.
please tell me how do I clear the menu cache?
lot of forums say that devel module has a link to clear menu cache. but I couldn't figure out one.
Please help me how do I clear Menu cache?
I cant go forward without seeing the page content.
your help is greatly valued

Probably menu_rebuild()
That runs menu_cache_clear_all(), among a few other things.

/**

function yourmodule_flush_caches() {
  cache_clear_all('*', 'cache_menu', TRUE);
}

Then to flush it manually inside your code, just call the function yourmodule_flush_caches;

admin -> settings -> performance

Click 'clear cache'.

Develop module: you need to enable the 'development' block. The link lies in that block.

Did you try hovering over the favicon in the top-left bar of admin menu ?

You can also go to /devel/menu/reset if devel is enabled.

Alternatively, if you are on a production site, don't want to clear all caches, don't have the devel module and have access to a PHPMyAdmin you can simply truncate (empty) the cache_menu table.

I should point out, as cog.rusty already said, that the easiest way to programmatically rebuild menu in Drupal 6 is to use the built-in method menu_rebuild() directly in your module's functions.

It clears the menu_cache table and rebuild all your menus.

Sincerely,
