Hallo, I'm writing from italy and sorry for my english
I'm new in joomla and using forms [img/]
I'm using visforms and I like it, compliments
I have a problem with a form at this link ( www.sharoncinema.it/index.php/casting-talentuosi ): when I submit it (button) it gives me this error:
Error: 404 - Category not found You may not be able to visit this page because of: an out-of-date bookmark/favourite a search engine that has an out-of-date listing for this site a mistyped address you have no access to this page The requested resource was not found. An error has occurred while processing your request
can Someone help me? Many Thanks!

Hi cosimo_palma,

I took a look at the link you submitted with your post.

There is obviously a problem with the searchengine friendly (sef) urls on your website which causes the problem with visForms. Usually visforms work fine with sef urls turned on. Without further information it's very difficult to help you.

I would like to have a look at the settings of your website. I would need to have an admin access to the backend for that. If you like me to have a look please send me login information at my contact mail (see below the forum).

Regards,
Aicha

risolto! thanks now it's working without sef
