I have split all of your replies from the previous topic.
Your issue is NOT the same. If you actually read the topic and not just the topic title, you would have known that the actual issue is not a file manager issue. File manager and FTP access was working, the files were just deleted.
Also, everyone who responded to this topic did not include a domain name or hosting account, so I could not check the issue.
Only @rowxitechnology shared a domain name (but didn’t actually post in this topic). And I just checked that one, and I didn’t see any issues.
All in all, maybe there was an issue, maybe there wasn’t. I have not have any way to check at any time.
Next time you need help, please make sure to include all relevant information, don’t just scream that it doesn’t work.
