good
I need to validate the css of my website, and there are some parameters of the chat code impiden.l I guess it's a tall order, but I needed to ask if you know how I can put this code in a manner consistent with validation.

http://validator.w3.org/check?uri=www.videatv.es&charset=%28detect+automatically%29&doctype=Inline&group=0

Go to modules/mod_freichatx/mod_freichatx.php

Replace

$document->addScript($host.'freichat/client/main.php?id='.$ses.'&xhash='.freichatx_get_hash($ses));

$document->addScript($host.'freichat/client/main.php?id='.$ses.'&xhash='.freichatx_get_hash($ses));

Sorry, but I didn´t found the mod_freichat folder. Where is it?

I said mod_freichatx in my previous post .

Have you not installed the module during installation.

And anyway , why are you so worried about validation. If there is any error
then it may be a matter of concern.

No, no module installed. I should skip that step. Where I can download now the module. It works without problem without the module. My concern is that validate the css seo optimized website, very important to me.

If you have not downloaded the module , you must have copy-pasted the code in the template.

Do the same changes in that code .
