Cannot load WPMUDEV Dashboard links

our WPMUDEV Dashboard only works for the "dashboard" link. All the others show this error message "Cannot load wpmudev-<name link>".
For instance :
WPMUDEV/plugins goes to "Cannot load wpmude-plugins"
WPMUDEV/themes goes to "Cannot load wpmude-themes"

We saw in the admin.php page that some files can't be found in the WP_PLUGIN_DIR directory :

if ( !( file_exists(WP_PLUGIN_DIR . "/$plugin_page") && is_file(WP_PLUGIN_DIR . "/$plugin_page") ) && !( file_exists(WPMU_PLUGIN_DIR . "/$plugin_page") && is_file(WPMU_PLUGIN_DIR . "/$plugin_page") ) )
wp_die(sprintf(__('Cannot load %s.'), htmlentities($plugin_page)));

And actually, we don't see any of these in :

Before we do something more, could you please help us? maybe it's just a thing to re-install or the cache to be cleared.

    I followed what you said and it didn't work.

    Actually, it's not only about the WPMUDEV plugins.

    Every link with the parameter "page" the url goes to "Cannot load #" (whre # is the parameter values)

    for intance :
    themes.php?page=theme-options --> "Cannot load theme-options"
    themes.php?page=custom-header--> "Cannot load custom-header"

    I've mase this test :
    admin.php?page=wpmudev-plugins --> "Cannot load wpmudev-plugins"
    in the "wp-content\plugins" directory, I added a file named "wpmudev-plugins" without extension
    admin.php?page=wpmudev-plugins --> no error but a blank page.

    hope it helps
