I just ran into a problem caused by my adblocker. it removed a portion
of the website that apparently was needed for jcarousel to determine
the dimensions of its object.
This caused a series of the above mentioned alert messages. I cant
even reconfigure my adblocker to not remove the element, because the
carousel effect is trigger every second, leading into a new alert
messages that blocks the whole window.
I my opinion, this message is good in development mode, but has no
benefit for the enduser and will likley confuse him/her. Alert
messages should be avoided in most cases, since they are very
intrusive.
I would fix the code myself (simply removing it), but i don't know
where the code is kept nor do i know what the usual approach would be
to such a problem.
