Somehow something is going wrong. I don't know how that can be because i haven't been in my admin or db for a while. But the problem is the full sized images are not showing anymore. Not when i use to open in popup and not in normal mode. Any idea's?
First thing to check is to ensure your storage options are correct in admin as if your large images do not show it can only be that or your watermark image if using on the fly watermarks is corrupt or not at the path your saying but at any url to the picture should help here
I don't use watermarks so what does that have to do with it? And it is so sudden without my interference or something. That's y it is such an odd error.
Go into admin global options change your url's etc to be what they should be and in storage options hit rever and save twice to load the corrected paths
