Error Upload File on Centos Server | ModSecurity: Access denied “MULTIPART_UNMATCHED_BOUNDARY” required
I have error when trying to upload file on my web application using centos server. Then i do something like this :
- I check my code for handling upload file and there’s nothing wrong, cause when i try in local server it’s work.
- I check php.ini configuration for max upload file at /etc/php.ini then make sure Maximum allowed size for uploaded files and all it’s great. upload max file is 128Mb. But i’m still got error.
- Then i check on log at /var/log/httpd/ssl_error_log and i got error message like this.
