Php Error with switch_language modul

[mylesk42]

Hello,
I've just encoutereed a problem with the switch_language modul :

Notice: Undefined index: 692 in /home/xxxx/public_html/xxxxxx/xxxxx/modules/switch_language/include.php on line 170

This line is repeated 6 times from index 687 to index 692.

I have other multi languages websites wit non problem. There was no problem until (I suppose) I've installed calendar-v2 + calendar month + calendar month link. I deleted the 3 moduls + the swtich language then re installed the switch language but I have the same errors.

An idea ?

I've just noticed that I have not created the same tree pages for the english language (they're not all created) like it's asked in the modul documentation.
Can anyone confirm this (before I finish to create the english pages) ?

I still have my problem while the EN pages are the same than the FR pages.
Any idea ?

Regards
