Are you out of space in your hosting account?
Mt client has unlimited disk space at that host.
Do you have access to your server error log? If so, generate the error again, note the date and time, then immediately check your server error log for any more descriptive errors that occurred during that time period. If you don’t have access to your server error log, ask your hosting provider to look for you.
So, I tried uploading another image and it worked, then I did another successfully. I’m leaving this open in case my client has more problems. Perhaps it was a problem at the host.
Excellent, hopefully it was a temporary issue.
