  Hey there!  If this is the correct value I'm thinking of, you'll want to edit /etc/apache2/conf.d/modsec/modsec2.user.conf and adjust the 

  SecRequestBodyLimit

  value to a higher number, and then restart Apache on the server so it is active.  Can you try that and see if that helps the situation?
