I received this error when upgrading from 1.3.11 to 1.4.5: 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 "Parser::replaceLinkHolders". MySQL returned error "1072: Key column 'name_title_timestamp' doesn't exist in table (localhost)". At first the upgrade would not even complete until I did this manually: alter table image add primary key (img_name); - Ken
