Hi I get the same message, but the item is saved, also the image.

I checked and in .../item.php lines 276 - 286 I see the following
if (($files == 0 || $existingImage) && !JRequest::getBool('del_image'))
{

if ($files == 0)
{
$image = $files;
}
else
{
$image = JPATH_SITE.DS.JPath::clean($existingImage);
}

There is no "===" to change.

I'm using K2 2.7.1, Joomla 3.6.5, PHP 5.5.38.

Any ideas?

Are you talking about the frontend or the backend?

The frontend

If you use the default template, is the issue still present?

Yes, I get the same error message

I've found out this:
When I set Image tab -->on from K2/frontend ediding the error message dissapears. When I set it off, the error is back again.
Any suggestions?

If you set the image to off then the field should not appear at all.
Is the field still present?

If I set image -->off, the tab (in the frontend) is not present.
Then I get the error message.
