[Tiki-users] Forum search is down

Hi

On https://tiki.org/tiki-forums.php , enter something in the search field
and click "Search in Content". Then this error message appears:

"Malformed search query: SQLSTATE[42000]: Syntax error or access violation:
1064 table tiki_main_692e5632d2904: alias 'tracker_field_u_user' must be
unique (conflicts with another alias)"

Cheers,
Volker
