Login Snippet / Login works not

Hello everyone,

i have a school website and i want a Login that the parents have login to some hide resources.
i installed the Login snippet i set a login page with the form:
[[!Login? &tplType=`modChunk` &loginTpl=`LoginChunk` &loginResourceId=`100`]]

i did exactly the example from here: http://rtfm.modx.com/display/revolution20/Making+Member-Only+Pages

but every time, after the login i cannot see the resources and i redirect to resource "100", i receive on title: Error 404: Page not found
or on content:
"
503 Error
Page not found
The page you requested was not found."

any idea what i do wrong?

regards and many thanks

Are you logging in as member of the User Group that has access to the Resource through the Resource Group Access ACL entry?

Is the Resource in a Context other than 'mgr' and 'web'?

yes.. here some screenshots...

in the content i have "web" and "de" because i use babel for a german language

http://www.modxcms.de/forum/comments.php?DiscussionID=6434&page=1#Item_3

i tried that.. also the &contexts=`web,de` but it doesnt works.
on the "web" context works, but not on "de"

Wouldn't the context access for the user also have to be added for the de context?

edit: NM, looks like you added that already.

do you mean this one?

Is that the resource group context or the user group context access? Either way, and I could be wrong, but anonymous wouldn't be part of either the user or the resource group, no?

Have you looked deeply at Bob's Guides and the permissions docs within?

This is also slightly helpful, visually.

I haven't done permissions with contexts yet, although I do need to soon, so I'll be watching this thread for my own benefit. :~}

Did you do Flush Permissions and Flush all Sessions after making the changes?

i did everything from Bob's description

here also my settings...
