"You may need to set LimitRequestBody 16777216 and memory_limit = 64M in /etc/php.ini and /etc/httpd/conf.d/php.conf on your Gallery server"
To solve the issue, change the /etc/php.ini file to
vim /etc/php.ini upload_max_filesize = 128M
Edit the following as well for /etc/httpd/conf.d/php.conf
vim /etc/httpd/conf.d/php.conf<Files *.php> SetOutputFilter PHP SetInputFilter PHP LimitRequestBody 33554432 </Files>
