Hi,

as discussed in this post: http://piwigo.org/forum/viewtopic.php?id=17944&p=1  (scroll down on the first page)

It seems that there is a problem with the advanced menu manager (or the Grum GrumPluginClasses)

After installing the Contact Form and Photoupload, the Links disapear in the menu.

I have posted this problem here again because in the thread header it is still showing [resolved].

Here some of my questions/notes:
+++
After my Test Installation I used the latest version for my site and I do not have the Photo upload option and do not have the contact option in the Menu.
The test Install uses:                   New Install:
Piwigo 2.2.4                                 2.2.5
Community Plugin 2.2 l                 2.2 l
Contact form 1.2.4                        1.2.4
PHP 5.2.14                                    5.3.3-7+squeeze1
mysql 5.0.91                                  5.1.49-3
Grum classes 3.5.1                        3.5.1
I am not sure if the PHP and mysql version matters.
On the Test install everything works fine on the new one no upload and contact function.
I would downgrade my install if I knew how to do?
+++
Is this problem seen somewhere?
Yes, I use Advanced Menu Manager r3.1.3 as well.
In the settings of this plugin under Menu Management and Content of Menu and Special  (I hope my German translation is right) there is also no text for Contact form and Photo upload.
So it looks like somewhere is a bug or version incompatibility.
+++
Is there a workaround?
How to fix it?
Is it may be dependend on the installation order? (means wich plugin first, which next)
I see that is also dependend on GrumPluginClasses 3.5.1, so this plugin is may be also involved.
Both are from the same author, how to contact him?
Can this be taken in the Bug fix list? (is there one?)
Sorry for so many questions, I like to fix it soon.
Any hint/tip is welcome, I will try to help to find the cause.

I will contact Grum to have look as well.

Joergen
