Slim Application Error when submitting paper file

*Dear support,

I faced the Slim Application Error when the user try to upload the paper document, i enabled the display_errors in debug setting, then the error is gone. However, the journal admin could not load the submission page, but he can login.

Need your help to solve this issue.

Regards

Hi @ahmed_faeq,

Are you able to check your PHP error logs and report on errors found there? Also, can you please indicate your specific version number (e.g. 3.3.0-13)?
