It seems you have melted two versions of K-Meleon.
1.1.5 doesn't use tabs, but layers, and the macro refers to a tab function.
I presume you have installed the two versions with the setup, and you haven't choosen for the last, when setting up, to uncheck the profile location.
Try to delete (or first rename your profile folder, launch K-Meleon : it will create a new profile. It ought to work correctly.
After, just keep some files in your old profile to put it in your new profile.
