Well-known member
After an import from vbulltin ( The import was accomplished succefully months ago), I noticed that the auto complete search feature is not working for imported members.


its working for all members when searching members in admincp, but working only for no-imported members if I search a member in this page. (https://xenforo.com/community/members/)
Can you help please?
