two separate forums having the same issue and error when trying to update using the "update your forum" link in admin panel:

Error in Package Installation
At least one error was encountered during a test installation of this package. It is strongly recommended that you do not continue with installation unless you know what you are doing, and have made a backup very recently. This error may be caused by a conflict between the package you're trying to install and another package you have already installed, an error in the package, a package which requires another package that you don't have installed yet, or a package designed for another version of SMF.

Stop Spammer doesn't play entirely nicely with 2.0.15 - have a read of the mod's thread where it is documented how to fix it.
