Issue

File upload failed because the file you attempted to upload was too big.

Cause

PHP needs to allow a bigger filesize.

Resolution

1. Log into your Control Panel and access your subscription and access the Websites and Domains tab.
2. Click on the Show More button, shown in the image below to display the PHP Settings link.
   
   
   
    
3. In the PHP Options, select custom value for both post_max_size and upload_max_filesize and set to a value bigger than the file size you need.
4. Click OK when finished.
