Warnings when using Accordeon Menu ck

Edit- Just realized that I tried the update on another instance of the site. I am now working with a clean backup.

I did not have the fatal error until I tried the helper file that you posted. Site was blank except for the fatal error wording. Once I switched back to the initial helper file the fatal error went away and the warnings returned.

The installed module is dated octobre 2011

Here is what is at the top of the helper file that I downloaded a few minutes ago that you posted.

<?php

ok so please update the correct module, if you have the warning again then replace the file that I have given and tell me.

It seems that there is a confusion here

So you want me to just download the new zip and install.... no other procedure?

sorry but as you have made some mistake I don't know anymore at which step you are ...

This is a clean backup. I don't think I have made any mistakes.
I have my live site which is untouched as far as troubleshooting and the error reporting turned off.

I also have a couple others of the same site in that I have been working on to try and fix the warnings. The one I am working on is a clean backup with no experimenting except for your helper file change.

I talk about this

Just realized that I tried the update on another instance of the site.

so if I understand now, you are in the same state as at the beginning with the warnings ?
which version of the module do you have ?
