Increasing Maximum File Size for CSV Import

I have attempted to look in a number of different areas for this, but have come up with nothing.

Checked the CSV Import in /var/www/plugins, config.ini, php.ini.

I have changed some areas to have a maximum file size of 30MB, but nothing has changed.

Any help would be appreciated.

Update! This is SOLVED. I was having difficulties locating the post_max_size in the php.ini file, but a simple string search helped me locate it.

Even after this was changed, however, it still returned a max file size of 2MB. A simple sudo reboot updated everything. All good now.
