Googling i found the error was in the size of LimitRequestBody, i change it to 64Mb but i still getting this error.

any ideas how to solve this?

Answer 1

It's what worked for me:

in modsecurity.conf file

On my Ubuntu 14.04 the config file is here but this really depends on the system:/etc/modsecurity/modsecurity.conf

change this two commands to this values:

SecRequestBodyLimit 13107200

SecRequestBodyNoFilesLimit 13107200
