HTTP Error and can't upload files on submission

Hi there, I can’t upload files on ‘Upload Submission File’ and got the following error on the log:

Http%20error

Any idea about the error?
Please kindly send related alternatives. Thanks

Hi @Untung_Wibowo,

None of the log entries are actual errors, they are just warnings, so they don’t give an indication of the problem.

Thanks @astevens

I am relatively newbie for PHP.
How do I solved this warning? Any setting to be adjusted?
Please kindly share any suggestion. :grinning:

Hi @Untung_Wibowo,

You can remove the strict standards errors from your log by following the instructions here: https://www.inmotionhosting.com/support/website/php/strict-standards-fix

Then I would try uploading a submission file again and checking your error log to see if there is an error reported.
