file upload error with undefined 500

ait1

There is a file upload error when our agents want to upload the PDF attachment, the error message is: undefined 500.
And the error.log:

The file size is 10 MB, but we were only able to upload the file size is less than 1MB, I changed the PHP's upload_max_filesize setting to 1024MB, but the issue is still there.

Please help. Thank you.

You need to upgrade to the latest release and retest.

Also, it's saying that there are no files to count; meaning the file failed to upload. You can right click the page, click Inspect, click the Network tab, click the button to Preserve Logs, upload a file, and click the request in the Network tab to see the response. This might contain a more detailed error.

Cheers.

I’m confused..your later screenshots show successful upload of a PDF. Is it an issue with just that one PDF?

Cheers.

KevinTheJedi when I upload the large file, the error happened.

Oh, okay. That wasn't clear initially. So your Apache probably has a limit as well. Please review Apache documentation on how to increase the max upload size, max post size, etc. Once you make the changes you'll have to restart Apache and retest.

Cheers.

KevinTheJedi Thank you. The issue is fixed, once I increase the size of the post_max_size on the php.ini of apache2.
