HI Andreas,

It looks like you are running into Bitbucket Server displays 404 j_bitbucket_security_check 

Please follow the instructions on the KB article and let us know if this resolves the issue.


Hi Edward,

Thanks for your response. I read the article and made the query. I've got just one result:

id        application_id directory_id list_index is_allow_all
65537 1                   32769         0              T

It looks okay for me.
