Issues Solved[edit]

This plugin is incompatible with MyBB x.x.xx[edit]

This issue occurs when an old plugin is installed onto a new version of MyBB. It does not necessarily mean the plugin is not compatible with MyBB, but fixing the issue will not guarantee the plugin will work.


  1. Open the plugin (php file) in a code editor
  2. Find the following line: "compatibility" => "xx*",
  3. Change the number xx to your MyBB major version

The number listed contains no dots and does not contain the minor versions, i.e. 1.6.14, rather the first 2 numbers are used. So if your MyBB version is 1.6.14, you would change the compatibility number to 16:

"compatibility" => "16*",

This issue occurs because a line of code is missing from the templates headerinclude file.[1]


  1. Open the MyBB admin panel
  2. Navigate to Templates & Style -> Templates
  3. Click on your active template
  4. Scroll down and click Ungrouped
  5. Click headerinclude
  6. CTRL+F var cookiePrefix = "{$mybb->settings['cookieprefix']}";
  7. Copy and paste this line after it: var cookieSecureFlag = "{$mybb->settings['cookiesecureflag']}";
