I'm having a problem where I get a blank page during the uploading process.
-I'm using Coppermine gallery 1.2.14
-I'm uploading using HTTP.
-Some images are uploaded and added to the gallery properly.
-Some images are uploaded, and thumbnails are created (seen using FTP). However intermediate images are nowhere to be found and the image does not appear in the gallery.
-Some images are not uploaded at all.
-I tried the instructions in the "Upload troubleshooting" of the documentation, however as all I get is a blank page there is no debug information to be copied. I checked looked at the debug information shown in the steps before I get the blank page, but they contain no errors.
-I searched through the forum and found that uploading problems can sometimes be caused something called "PHP memory limit". I checked the support forum for my webspace provider, and it turns out I have 20MB.
-The image I am trying to upload is pretty large, 2560x2048 @ 8.32MB (PNG). Though I don't think that is the problem as I have other images in my gallery that are of the same size.
-I tried to upload an image that was already available in my gallery (under a different name), but it didn't work. So the problem must be a recent one.
-I tried to upload a much smaller image, 800x600 and it worked fine.
-I re-uploaded all of the .php files from my harddrive over to the site and selected the default theme, it didn't help.
-This is the first time I have experienced this problem.
Could it be that my PHP memory limit has been suddenly reduced, or is Coppermine gallery using up more memory than it is supposed to?
