Tried to log in today and got this message:
A database query syntax error has occurred. This may indicate a bug in the software. The last attempted database query was:
(SQL query hidden)
from within function "User::idFromName". MySQL returned error "1142: SELECT command denied to user 'wiki_user'@'localhost' for table 'pw_user' (localhost)".
I also get this same message when trying to view some pages, such as my global name page.
