Save&view of pages does not work

Hello,

it seems that there is a general bug in XWiki in 10.10 and 10.11.*
If I want to create a page or a glossary entry, the following message is displayed when I click “save&view”:
XWiki%20Error

After a while the error message disappears. Then I refresh and can see the created page/entry.
This is very vexing for users.

Can anyone confirm this problem?

Thanks a lot!
