Description of my issue:
After many months of successfull backups of one of my sites, it suddenly stopped working 2 days ago. I guess something changed on the server at my host (it's the only website that's still being hosted at Versio.nl, the others are at Siteground). I don't think it's caused by updates because the last round of updates I did was 2 weeks ago and the backups started failing 2 days ago.
My backups are triggered every night by a cron job. Today I started them manually from the backend and it fails. The first time I ran the troubleshooter it gave me 2 warnings: to many tables to backup and archive part size not set. I fixed these warnings but the backup still fails.
I get this error message:
Backup Failed
The backup operation has been halted because an error was detected.
The last error message was:
AJAX Loading Error
HTTP Status: 0 (error)
Internal status: error
XHR ReadyState: 0
Raw server response:
I also checked the servers disk space but that's no problem. More than 7GB free.
I've tried to go through the log file but I don't know what to look for. I tried to search for the word 'error' but that only returned files with the word 'error' in their names. And 'failed' didn' return anything.
So I'm a bit out of options now.
Can you help me find out what's causing these failed backups?
Thank you.
Kind regards,
Jan Buskens.
