*Caution: You should not edit this file if you are not confident in the code. You shouldn’t really change the upload_max_filesize for purposes other than importing.

For wordpress upload go to /etc/php5/apache2

Vim php.ini

Search for upload_max_filesize and post_max_size by writing / before the word.

Instead of copying the wording just change the number.

Do sudo service apache2 restart.
