Thank you all for your patience while the admins have looked into the issues causing the 500 server error message to pop up, as well as the inability to upload attachments. We have found the source and due to that, we will be working on the fix. This fix, however, means that attachments will be TEMPORARILY UNAVAILABLE as it runs the process to fix it. That said, PREVIOUS ATTACHMENTS may not load until this fix is completed.
We'll update the member as soon as we can!
Thank you all. :)
