Finally! I Found it.

I have a lot of redirects, about 700 and 1 of the redirects was:
Redirect 301 /wp-content/themes/enfold/framework/ http://WEBSITE.nl/
I dont know why i added that redirect. I think it was in the list of webmastertools.
I removed that line and that solved the problem.

Thanks.

Michel

In register-admin-options, i printed:

echo '<p r e>';
print_r(get_defined_constants());
echo '</ p r e>';
echo AVIA_IMG_URL;

the avia_img_url is defined in get_defined_constants, but it is empty when echo’ing AVIA_IMG_URL;
