Blank screen when accessing menu in admin

    Receiving a blank screen when selecting the Menu from the admin for some sub-sites (not all). Also receiving the blank screen when trying to remove a custom navigation item from the main site.

    When first occurred I was receiving a 500 server error that had: A misconfiguration on the server caused a hiccup. Check the server logs, fix the problem, then try again.

    I checked the server logs and found an error that had: Failed loading /usr/php/54/usr/lib64/php/modules/ZendGuardLoader.so: /usr/php/54/usr/lib64/php/modules/ZendGuardLoader.so: undefined symbol: zend_new_interned_string

    The host installed IonCube. This didn’t fix the issue however the 500 error went away and now I receive a blank screen.

    The host doesn’t support wp Multi-site so won’t help trouble shoot.

    The main site is: http://insightinnovation.org – I was trying to remove the GreenBook Directory nav item from the top navigation (which is an external menu item) when I receive the blank screen.

    Also, for one of the sub-sites, http://iiex-eu.insightinnovation.org, when I try and access the Menu from the admin, I receive the blank screen.

    Any recommendations or suggestions on how to resolve would be appreciated.

    My guess is that you may have a problem with a plugin or theme. Have you enabled a specific plugin/theme for those problem sub-sites. You can try to turn on debugging to see what the error is by adding this to wp-config.php

    define('WP_DEBUG', true);

    The site loads for me, as does http://iiex-eu.insightinnovation.org/wp-admin …

    The main site is: http://insightinnovation.org – I was trying to remove the GreenBook Directory nav item from the top navigation (which is an external menu item) when I receive the blank screen.

    How were you removing it?

    Hello

    The blank screen displays through the wp-admin when trying to access the Menu in the http://iiex-eu.insightinnovation.org site and when trying to remove a navigation item in the http://insightinnovation.org site.

    I’ll turn on the debug this evening (when there is less traffic on the site) to see what shows up. I haven’t tried this yet.

    What URL is that menu link taking you to?

    In http://iiex-eu.insightinnovatio.org/wp-admin when I select Appearance-> Menu I then receive a blank screen – url in address bar is:
    http://iiex-eu.insightinnovation.org/wp-admin/nav-menus.php

    In http://insightinnovation.org/wp-admin when I select Appearance->Menu then try and remove a navigation item (select nav item, select remove, then Save), I receive a blank screen.

    I turned on debugging and am using the Debug Bar plugin, this shows one Depreciated notice:

    • wp-admin/menu-header.php:144 – Usage of user levels by plugins and themes is deprecated. Use roles and capabilities instead.
      require_once(‘wp-admin/admin-header.php’), require(‘wp-admin/menu-header.php’), _wp_menu_output, current_user_can

    I have one notice/warning for plugins:

    • NOTICE: wp-content/plugins/wp-rss-multi-importer/inc/upgrade.php:15 – Undefined index: plugin_version
      require_once(‘wp-admin/admin.php’), do_action(‘admin_init’), call_user_func_array, upgrade_db

    Hello – all fixed. Seemed that the wp-rss-multi-importer plugin was creating the issue. The plugin was Network activated and once I disabled this, I’m able to access the Menus through the admin.

    thanks for the quick feedback.
