Allerdings habe ich keinen Cookie der mit 4images_ anfängt....
I do not speak this language
but according to what I understood (and what I saw on your site),it does not work for you and you don't find the cookie...
this code:
$cookie_name = (defined("COOKIE_NAME")) ? COOKIE_NAME : "4images_";
checks if the name of the cookie were already defined.
if it is true, the cookie will use this name (
=> it's your case.)
if it is false, a new name (in this code
4images) is defined for a new the cookie.
the problem is as follows: when you refresh or load a new page, it is not possible to know which style to use in your page because the information about the style is not stored in your cookie(you should find
in your cookie an item called
4images_design, but...no trace )... then default style is used.
: can you reach the logs of your php server and if so, can you find errors about cookies creation (or writing) about the creation/update line?
