The last couple of days, I've been running into pages requiring two attempts to load. For example, I'll click on a link to a gallery, and I get a blank page (but with the full, correct url in my browser's address bar) If I then click reload, the page will load completely. This will happen multiple times throughout my visit.
Similarly, I just went to add a gallery to my favorites, and the Add To Your Imagefap Favorites button just pinwheeled after I clicked it, until I reloaded the page. It worked as expected after.
