frontblock_type errors

[Ken.]

SMF 1.1.2
TP 0.9.7
Mod Name Version 
1. MySpace Field 2.4
2. Users Online Today Mod 1.4.0 
3. SMF 1.1.2 Update Package 1.1.2

My forum error log generates lots of pages each day with most of them like the ones you see below.
Not sure if itââ,¬â,,¢s just a TP issue, or SMF, or both???
So far my efforts are not finding an answerââ,¬Â¦ any help would be most appreciated! 
Thanks, Ken

EDIT: had to change the installed mods list! I have two different forums and posted the wrong mod list for this one
