For some reason, the portfolio and other galleries are not loading on initial load, but will load when you make a refresh of the page. The problem re occurs if you go to a page and then go back to the initial page again. The problem is (as far as I can tell) only occurring in Safari.
I've tried to clear the cache, but the problem is still persistent.
The site can be found at http://www.olgulve.dk and the affected pages are the frontpage (Might have to navigate away from it, and back, for the issue to appear), and another affected page is this: http://olgulve.dk/undergulve/
I hope that you are able to help me.
