Issue Clicking on Backup triggers the error: Warning: Permission denied.

[enerspace]

Server operating system version

Almalinux 8.10

Plesk version and microupdate number

18.0.68 Update #2

Hello everyone,

I have the problem that when I go to the Backup Manager as user: admin and click on "Back Up", I end up on the dashboard with the error message: "Warning: Permission denied."

However, backups can be carried out via CLI and scheduled.

Does anyone have an idea what this could be caused by?

I have already tried several approaches:

• Plesk repair all
• Delete SFTP Addon

Error in the log files:

PleskPermissionDeniedException: Permission denied.

Hello, @enerspace . Assuming that you don't have restricted mode enabled, I would recommend temporarily enabling Plesk debug mode, reproducing the issue and checking the panel.log for additional details. I know that in the past users experienced similar issues due to modules with empty name value.

Hi @Sebahat.hadzhi, what should I look for in the log files?

 

[Sebahat.hadzhi]

The entries logged before/after the PleskPermissionDeniedException: Permission denied, specifically SQL entries (if the issue is the same in your case). If you can provide what's logged at the time of the issue, it will be great.

Hi @Sebahat.hadzhi,

Here the log file:

How can I fix the error?

Can’t the error also be fixed by the Plesk repair tool in the future?

What's the output of these commands?

ls -ld /usr/local/psa/PMM/tasks && ls -l /usr/local/psa/PMM/tasks/

ls -ld /usr/local/psa/PMM && ls -l /usr/local/psa/PMM/

Plesk Repair may not catch an incorrect permission if it's on the parent directory, so please that to check.
