Version-specific Problems


1.1.x and 1.0x


Host-specific Problems

  • x10hosting - There is a known issue with MyBB 1.2 not working with x10hosting due to them having both eval and exec turned off on their hosting accounts by default. To use MyBB 1.2 on x10hosting you must contact them and request that eval and exec be enabled on your account. It also seems that they now have phpinfo turned off by default which causes the CAPTCHA to function incorrectly, if this happens to you, please request that phpinfo be enabled on your account.

Common Modifications

Other Questions

  • Can I remove the MyBB copyright on my forum? Yes and no. According to our license, you are free to remove the copyright from your templates (but not from the source code). However, to receive support at the Community Forums, you must consistently have the MyBB copyright in tact. Forums that do not have the copyright or add the copyright to ask for support (and then remove it again after their support question is solved) will not receive support.
