aqua-soft style
 

after i have installed aqua-soft style i have this problem :

Your submission could not be processed because a security token was missing or mismatched

Way ?

Se c'è qualche italiano che mi sa rispondere, sarebbe graditissimo, altrimenti cercherò di arrangiarmi con l'inglese.

Not a good idea to run this then. The tedious task of adding security token updates to every form could take a while. You are better off cannibalizing the them to a stock 3.7.0 theme.

Please request support from the author of the style. But if you were to solve this yourself, you would have to add the security tokens to every form found within vBulletin.

i have asked..
This is the answer:

It's because skin still not officially updated for 3.6.10. You can find solutions on vbulletin.com/vbulletin.org forums, it was described lots of times..

You have to add the security token fix that is listed as a sticky on vb.com under every form.

Member instructions can be found within the vBulletin article section here at vB.org.
