The MyBB 1.6 series reached end of life on October 1, 2015.

This means there will be no more security or maintenance releases for these series and forums running these versions of MyBB may be at risk of unfixed security issues. All administrators are strongly encouraged to upgrade their forums to the latest release of MyBB as soon as possible.

  • Prefix - Its an option which show thread prefix on thread prefix option list on new thread pages and edit post pages.
