Suddenly my website is falling apart.. First I use NextGen gallery and suddenly I could not upload more photos in the normal way and when I have clicked on upload photos, the next page where I supposed to do it was empty. Also since this happened, I can not drag anything in to the footer, it just doesnt work. Like its only letters and not a plugin. I can not edit thumbnails anymore, same thing like with the footer. When I try to choose what part of the photo I would like to use, it try to move the whole photo. Not long ago, without doing anything, this has appeared on the top of my home page! NOT found /jquery-1.6.3.min.js was not found on this server. http://www.4llw4d.freefilesblog.com IT is really annoying and I dont know how get rid of it. Should I upload my header as well, it would be greatly appreciated if someone could help me out. WordPress and everything seems to be more and more complicated to me.
