[TYPO3] te_advDivider problem

[Stan]

Hi

I upgraded a 7.1 installation to 3.8


I have some probs with te_advDivider

I just put a new news item in and got this error.

ERROR: Content Element type "te_advDivider_pi1" has no rendering definition

When I first upgraded i had a total breakdown because of this extension so I 
deleted it and reinstalled it. Eventually I deleted the folder for it and 
tried again and the site seemed okay, but it seems now there is still 
something wrong.


Any help would be appreciated.

Regards Stan
