I've recently upgraded my forum from vB 3.8.x to vB 4.2.1 and have an issue about new uploaded attachment images not showing proper thumbnails. They simply show "question mark" images instead. When trying to rebuild attachment thumbnails, I get this error multiple times:
Processing: Attachment : 1 (jpg) Error
Attachments are stored in the file systems. The attachment directory and its sub-directories have 777 permission. At the moment, the owner and group of the attachment folder is the same as the rest of the other vB files in the hosting account. (I've also tried changing the owner and group to "apache:apache", but this didn't help.) Would anyone have any ideas what else I might have missed, please?
