This problem will be fixed in the next release version. For now, follow the instructions below to work it out:
- Replace your files with 3 attached files.
MassMailer.pm ( in admin/Dbsql directory ); mph-email.cgi ( in admin directory ) and Dbsql_MailingIndex.def ( in admin/defs directory ).
- Add a field called 'user_table_use' (varchar(70)) onto Dbsql_MailingIndex table by using MysqlMan tool
If you have any questions about this, please let me know.
