I recently upgraded to version 13.10,8.
When i try to create a sub wiki I get the following error message:

Any help would be greatly appreciated.

Unfortunately the root cause is not printed in your stack trace because our code wasn’t good. I’ve fixed it at [Misc] Add missing exception · xwiki/xwiki-platform@8d0dd49 · GitHub

Maybe try to navigate to document technical:WikiManager.WikiUserConfiguration to see if the doc exists and can be accessed.

#3

I cannot navigate to the page. Immediately after the error is thrown, Xwiki is deleting and cleaning up the failed wiki creation.

#4

When I create the new wiki, it looks like the database is created, but none of the pages are created. In Catalina.out this error:
“java.sql.SQLSyntaxErrorException: (conn=2467) Specified key was too long; max key length is 767 bytes” led me down the path to upgrade mariadb from version 5.5 to version 10.8.

Upgrading mariadb solved the problem.
Thank you
