your php configuration limiting size of post data 3mb. load larger file need change couple of items in php.ini. can determine location of php.ini php_ini_loaded_file() - see this answer
post_max_size sets maximum size of post. refers all data in post - uploaded file(s) , form variables. need raised 5mb (larger if want handle bigger files)
you'll need set upload_max_filesize larger, smaller post_max_size. again, determine size of files you're need , set accordingly.
these values set in system-wide php.ini file. configurable through .htaccess or php.ini file in application directory; others can set programmatically ini_set(). references have linked tell can set different parameters. reference configuration mode settings here
note hosting companies limit can on cheap (or free) hosting packages. might not able change if you're on free package. there's no work around: better host, , pay if necessary.
