Maximum file size for uploads

[Meddysong]

I'm unable to upload some of my files to my site because the limit is 7mb and these files exceed it. What I can't understand is where this limit is set.

I've checked the php.ini in my domain's root and that contains

upload_max_filesize = 20M

I've checked in the server root too. (My site is located in an addon domain.)

upload_max_filesize = 50M

I can't see anything in conf_global nor locate any settings in the ACP. What am I missing? Where could this limit of 7mb be coming from?

Solved it. It's not upload_max_filesize which controls this but post_max_size.
