Hello again,

Having debugged the issue on the shared hosting, I have discovered the following. In the plugin’s class-create-archive.php, there is a function called posix_getpwuid(). It translates a file’s UID and GID to their corresponding names.

On this shared hosting, the first part (call to posix_getpwuid()) succeeds, but the second part (call to posix_getgrgid()) fails and returns FALSE. Therefore the following statement $group = $info['name']; fails with the original error: “Trying to access array offset on value of type bool”. Now that finally makes sense ?? .

I propose to safeguard against this possibility by rewriting the calls like this:

if (function_exists('posix_getpwuid') && ($info = posix_getpwuid($uid))) {
    $owner = $info['name'];
}
if (function_exists('posix_getgrgid') && ($info = posix_getgrgid($gid))) {
    $group = $info['name'];
}

Would you please consider adding this safeguard to the plugin’s official source code?

Thanks,
FWieP

Hello again.

I have followed in your footsteps and installed a clean WordPress with your plugin on a local test machine using PHP 8.2.

You are correct: there are no warnings during execution or in the logs. The warnings I get in the original post, I will have to debug myself on that specific shared hosting server… ??

Thanks for your effort and support,

Hi, thanks for your reply.

I have disabled all other plugins and ran the Job ‘dataabase only’. It still generates 6 warnings.

This is the system info:

I see the same PHP, WordPress and plugin versions.

This is the logfile of this job:

Is there anything else I can try?
