[TYPO3-templavoila] "invalid template values"

[Paul Bucalo]

I'm getting a series of errors broadly labeled as "invalid template values".
Is there a place to reference the specific errors?
Here is one for example:

> Main Content Area (field_content)
>
> "Pick the HTML element in the template where you want to place the main
> content of the site."
>
>    - the entered/computed value will be passed to htmlentities [HTML-code
>    will be displayed as-is]
>
> Preset used for the element:Content ElementsColumn-positioning:Normal [0]
> TypoScript:
>
>    - 5 lines of TS-code inside the <TypoScript>-entry
>
> I clearly see the error message, but I'm not sure where in the XML to make
the change.
If anyone can point me in the right direction I would sincerely appreciate
it.
Thank you,
Paul Bucalo
