I figured out the problem. I am using MediaPress because I need the Watermark functionality and I don’t see that available in BuddyBoss. The problem that was occurring is the Watermark image that I was using could not be found therefore the error that occurred was during the watermarking process which then messed up the thumbnail generation processes. After pointing at the right watermark image, the photo upload now works. Thanks.
There is plenty of space available for uploads and as indicated, the image is successfully uploaded but there seems to be a failure in the generation of the thumbnail and that is when the “<file name>.jpg(38 kb)x HTTP error.” appears. I am not aware of additional media plugins. I downloaded BuddyBoss and MediaPress and it was working fine but suddenly stopped. I’m shocked nobody else has run into this but it is extremely aggravating because all photo uploading functionality via BuddyBoss now doesn’t work properly.
