  1. May I point out again that if you are upgrading from 1.4.6 there is no upgrade script for this upgrade. You just need to upload the changed files or manually make the edits.

  3. Went as smooth as a babies butt! Thanks myBB, you’re all the greatest. We’re leaving SMF in the dust!

  4. MyBB…… You complete () Me :)

    Thanks for the patch. Upgrade was super simple and without issues.

    Keep up the great work !!

    Cheers !

  5. Had this exploited and the whole forum was deleted… lesson definitely learned (and patch applied). Thank goodness for my awesome hosts who keep daily backups.

  6. My forum was attacked with an exploit while i was upgrading to the newer 1.4.8 version from 1.4.6 and another from 1.4.5, the attacker gains administrative access via an exploit which is now posted on milw0rm.com searched simply under “mybb”.

    The patch most certainly fixed the problem.

  7. since I like to know what happens, I downloaded the patch instruction and am applying it manually.
    Seeing that you need to escape birthdayprivacy, it strikes me as odd that the same precaution would not apply to birthday, just a few lines above in user.php.
