Can you check the following settings in your php info?

upload_max_filesize
post_max_size

These values needs to be greater than 20mb if you are trying to upload something that is about 20mb.

Hey Mark ... I confirmed that the upload_max_filesize and post_max_size were set to 64M prior to opening this ticket. Feel free to create a test entry to confirm. Thanks!

Hi Brad,
Can you also make sure the following setting has the allowed max file size?
Settings>Media>General>Uploader>Maximum upload file size(http://take.ms/JqslK)

If the issue persist, can you provide us your backend and ftp access as it seems your backend is blocked.
Our office IP: 124.13.241.185

Hey guys ... I checked the Setting you listed. It is set to 150 MB. However, beneath the field, it says "Maximum upload file size specified in PHP is 2M. Maximum post size specified in PHP is 8M." Can you direct me to the correct PHP.INI file to modify? I looked at the PHP.INI file at the root of my Joomla directory and the administrator folder.

I've also allowed access from the IP specified. If you are still unable to access it, let me know and I will temporarily remove the restriction. Thanks!

Hello Brad,

You would need to check with your hosting provider because not every hosting provider allows you to override the ini file. If this is your own server, by default the php ini file is located under /etc/php.ini

There was a limitation set on my ISP PHP settings, not within my Joomla instance. Adjusted the settings and able to upload fine. Thanks for your help!

Thanks for updating Brad, glad that your issues are resolved now
