the problem is that logo that is image and that was uploaded by webmaster and one that can not be uploaded by content management system(administration panel) is not displaying any more. there are no broken links (for example red cross and other) on the place of image. in a word it has totally disappeared. it was working fine in the past. it displays in no browser. please explain me in non technical terms so that it will be comprehensive for non webmasters. what could happen and tell me about all possible causes.
