Hello.
I install new Joomla, new K2, Takai template and latest update.
Only.
And I see in PA:

Warning: SimpleXMLElement::attributes() [simplexmlelement.attributes]: Node no longer exists in /home/public_html/libraries/joomla/form/field.php on line 864

Warning: property_exists() [function.property-exists]: Node no longer exists in /home/public_html/libraries/joomla/form/field.php on line 867

This lines are:

864

$attributes = $this->element->attributes();

867

if (property_exists($attributes, $name))

Can you help me? :)

Hello,

Are you using the latest version of the templatE?

Yes.
I download and install:
- latest version Joomla,
- latest version K2,
- latest version Takai template,
- update Takai template.

I will look into it.
The file is a core Joomla! file which cannot be altered.
I will need to look which template file is to blame.

OK.
It's my first contact with K2 and Takai template.
And my new websites - test new extensions.
Now I wait.
Thank you.

For the time being you can disable error reporting.
