[TYPO3-templavoila] TO is lost after updating

[Lim Chivy]

Hi list,

I updated the templavoila form v1.3.3 to v1.5.5, and it does not work 
cause of losing the template mapping object (TO). I have noticed the 
field "templatemapping" of table "tx_templavoila_tmplobj" were changed 
fied type form "mediumtext" to "mediumblob". Then I change this field 
type back manually in the phpMyAdmin, then it works. Does anyone know 
how to solve it?

Regards,
Chivy
