[TYPO3-templavoila] [TYPO3]Preview icon of data structure and Template Object

[Xavier Perseguers]

Hello Tong,

> I have 3 FCEs and each of them has one preview icon for data structure and one preview icon for Template Object. But in the view of FCE the Thumbnail can not display correctly.
>  
> For backend user, the preview icon can not display, but just display "invalid value 11". Who knows what is wrong? Thanks very much. 
>  
> For Admin user the preview icon can display.

You have to grant read access to the TemplaVoila DS/TO for the users in
their user group.
