I have problems by using the menu manager.
When I try to add a menu item for an external link, it tells me that I forgot to enter a function.

Also with the other menu types there is no button to enter the input. Only a "BACK" button is visible.

Dit I miss something?

With the type "custom link" all works as intended for me.

I can send you a screencopy, showing the error message I get, when I know where to send the image

Why don't you paste the error message right here? Otherwise if you think this is a bug please open a ticket.

I try to create a menu item of type Custom Link .
After entering the URL in the input box I hit return (there is no Button to enter)
On top of the form the following message shows:

You forgot to provide a function!

I am not able to reproduce that with Zenphoto 1.4.1.1.

Hi acrylian,

I found the problem with the Menu Manager.

It is nescesary to have the Zenpage plugin enabled to make the menu manager work properly.

Thanks for your time.

That should not be the case. Open a ticket.
