You are likely to be using a core-based theme. The reason it fails is because the stats template is completely different to the one in the default theme. The mod supports the core theme by targeting it specifically but it cannot tell if the theme you are using is based on core. You can still go ahead and install the mod and it will work fine with the caveat that the stats page won't have the thanks stats and the buttons will look a bit out of place because of the styling. To add support to your theme simply follow these instructions, for this example lets say you are using Back-n-Black theme: - Install the mod as usual making sure to install in core and your custom theme, it will warn you about your theme that failed the test, you can continue - Rename the Stats.template.php in \Themes\backnblack_204 to something else for example Stats.template.backup.php - Copy the Stats.template.php and SayThanks.template.php from \Themes\core into \Themes\backnblack_204 - Copy the Say Thanks style sheet from \Themes\core\css\saythanks.css and place over the styling in \Themes\backnblack_204\css\ (this step is optional, without this change the buttons look a bit thicker because the icons are doubled up but still look ok) Now the stats page and little icons next to the Say Thanks links should be working. You just need to make sure you do the reverse of the above steps when you come to uninstall.
