I am currently working on a digital archive on Omeka and want to post images on it. However, whenever I try to upload an image by adding a file, a webpage titled "Omeka has encountered an error" appears. I'm aware of the fact that I need to resolve this issue by making some changes to the configuration of my Omeka installation as well as the permissions, but nothing changed when I followed the directions from previous forum posts. Can anyone please provide some much needed and detailed assistance with this matter? Thanks in advance.
