I’m using WAMP which is the windows version of MAMP and the php.ini file I changed was located in wamp\bin\apache\Apache2.2.17\bin and I changed line 886: upload_max_filesize = 2M, changing this to 1000M got it up to 64M in the media uploads in wordpress, for a lot of people this will be enough but I’ve got some large video files to upload so I needed more, so I changed line 734: post_max_size = 64M to 1000M and it got me up to 1GB in the media uploads. Don’t forget the restart the server after making the changes
If your on a hosted server and you have this same problem you can try this;
Create a php.ini file (with a text editor)
with the following contents and upload it to the WordPress wp-admin directory :
<?php
memory_limit = 64M
upload_max_filesize = 1000M
post_max_size = 1000M
