Issue when uploading past 8MB?

In your php.ini make sure you’re changing both of the following lines.

upload_max_filesize = 250M
post_max_size = 250M

If you are using FastCGI as your PHP engine you’ll also need to up its limit in Apache. Try adding FcgidMaxRequestLen to your VirtualHost (see http://httpd.apache.org/mod_fcgid/mod/mod_fcgid.html#fcgidmaxrequestlen for more info on the directive).

Finally, if you’re on NGINX you might need to set

client_max_body_size 20M;

You’ll do this under the http section of nginx.conf (see http://wiki.nginx.org/HttpCoreModule#client_max_body_size for more information)
