XWiki 13.10.03 - Failed to save the page. Reason: Server not responding

Help / Discuss
#1

Hello,

I’m having a problem while trying to update the page for a group in XWiki with new members.
The error on the interface says " Failed to save the page. Reason: Server not responding."
I would like to add that I can update other groups fine, only this one (XWikiAllGroup) is acting out.
Did anyone else encountered this before? Could you please help?

Thank you.

Hi @Dan,

XWikiAllGroup is one of the 2 default groups (the other one is XWikiAdminGroup) provided by XWiki Standard.
By default, any user you create, will be added in this group. If you want to add or remove users from this group, then you could be on the wrong path regarding XWiki rights and membership.
If you’re trying to provide different permissions to different categories of users, you can take a look at https://www.xwiki.org/xwiki/bin/view/Documentation/AdminGuide/Access%20Rights/.

Hope it helps,
Alex

Hi @acotiuga,

Thank you for your response.
The problem that I am having is that the XWikiAllGroup is not being updated with new profiles anymore, so I was trying to update it manually. But when I hit save, it throws the error above.
And I’m trying to understand why, and how to fix it.

Br,
Dan

Dan,

If the XWikiAllGroup is not updated anymore, then this is the problem I would focus on. Have you identified the cause of this behavior? What XWiki version are you using? How are the users created (registration/added by admin)? Are there any error from the user creation step?

Hi Alex,

We couldn’t identify exactly why this is.
Even when it was working in the past, it was working about 90% of the time, and I had to manually add the rest of the users to XWikiAllGroup. The current problem started when I have made multiple modifications (adding 2 users at once and didn’t wait for the message “Members succesfuly added” and I hit “Save”). From that point on I started receiving the error above. And I can’t save any modifications to the group.
I use XWiki version 13.10.3.
Users are created automatically from an LDAP Database through the LDAP extension.
I didn’t see errors from the users creation step.

Best regards,
Dan
