[TYPO3-calendar] Upgrade 1.3.3 -> 1.6

[Loïc Stéphan]

Hello,

 

We have to upgrade cal extension from 1.3.3 to 1.6 (TYPO3 6.2) but we have a
problem with the updater script :

An error occured ! Invalid form/module token detected. Access Denied! (frame
URL :
typo3/mod.php?id=0&M=tools_em&CMD[showExt]=cal&SET[singleDetails]=updateModu
le).

 

We hope someone can help us.

 

Thanks.
