Fatal errors creating menus and menu items

[Amongthegums]

Hi
I get the following fatal error when trying to create menus or menu items:

Code: Select all

Save failed with the following error: exception 'UnexpectedValueException' with message 'MenusTableMenu::_getNode(1, ) failed.' in /home2/userdomain/public_html/libraries/joomla/table/nested.php:1542 Stack trace: #0 /home2/userdomain/public_html/libraries/joomla/table/nested.php(783): JTableNested->_getNode(1) #1 /home2/userdomain/public_html/libraries/legacy/table/menu.php(215): JTableNested->store(false) #2 /home2/userdomain/public_html/administrator/components/com_menus/models/item.php(1254): JTableMenu->store() #3 /home2/userdomain/public_html/administrator/components/com_menus/controllers/item.php(267): MenusModelItem->save(Array) #4 /home2/userdomain/public_html/libraries/legacy/controller/legacy.php(728): MenusControllerItem->save() #5 /home2/userdomain/public_html/administrator/components/com_menus/menus.php(18): JControllerLegacy->execute('apply') #6 /home2/userdomain/public_html/libraries/cms/component/helper.php(380): require_once('/home2/userdomain...') #7 /home2/userdomain/public_html/libraries/cms/component/helper.php(360): JComponentHelper::executeComponent('/home2/userdomain...') #8 /home2/userdomain/public_html/libraries/cms/application/administrator.php(98): JComponentHelper::renderComponent('com_menus') #9 /home2/userdomain/public_html/libraries/cms/application/administrator.php(152): JApplicationAdministrator->dispatch() #10 /home2/userdomain/public_html/libraries/cms/application/cms.php(251): JApplicationAdministrator->doExecute() #11 /home2/userdomain/public_html/administrator/index.php(42): JApplicationCms->execute() #12 {

Can anyone enlighten me as to what the error means and if there is anything I can do about it?

PS: Joomla 3.4 and I have done several clean re-installs to try and overcome the problem, without luck.

With thanks

extension manager/ database/ Fix

Thanks for the reply, but I had already tried that several times. No joy

Code: Select all

Database schema version (in #__schemas): 3.4.0-2015-01-21.
Update version (in #__extensions): 3.4.0.
Database driver: mysql.
80 database changes were checked successfully.

I just noticed I cannot "Empty" the menu Trash list. Again I get fatal errors indicating relationships are preventing it "emptying".

How can I clear all of the menus and their items in an attempt to start again?

Thanks

Anyone?

My Apologies. It turns out that the problem is with something called "Helix Mega Menu" that came with a commercial template I had purchased. It seems when the column value is > 1 the errors listed above occurs.

Have a look at the version of PHP that you are using and the version of PHP that is recommended for the version of Joomla

Try Use localhost (XAMPP)
