Problems uploading very large documents can occur for a variety of reasons but the most common by far involve the server's PHP settings. Follow these instructions and you are more than likely going to solve any problem you may have. - Login as administrator
 - Click on the Server Information link on the frontpage
- In the page that appears look at the three settings:
- Memory Limit - Should be set to something above the maximum file size you want to set
- Upload Max File Size - Should be set to the maximum file size
- Max Post Size - Should be set to the maximum file size
- If any of the above settings are too low, then you have to edit the PHP settings file php.ini.
- In it, look for these settings:
- memory_limit -
- post_max_size
- upload_max_filesize
