Modify the PHP file upload limit
Follow the steps below:
Modify the following options in the /opt/bitnami/php/etc/php.ini file to increase the allowed size for uploads:
; Maximum size of POST data that PHP will accept. post_max_size = 16M ; Maximum allowed size for uploaded files. upload_max_filesize = 16M
If the default Web server configuration limits are too low for the file sizes you plan to upload, you can also increase those limits in the /opt/bitnami/apache/conf/httpd.conf file, by setting the LimitRequestBody parameter to a new value in bytes, as shown below:
Restart the servers for the changes to take effect.
$ sudo service bitnami restart
