PhpMyAdmin Import Fails with warning: "POST Content-Length exceeds the limit"

Symptoms

If you are attempting to import a database or .sql file in PhpMyAdmin and you encounter this error:

phpMyAdmin - Error: Incorrect format parameter

This usually indicates that the PHP limits for upload and post_max_size need to be increased.

Description 

The PHP values for max upload size and max POST size that PhpMyAdmin will use are set inside WHM's tweak settings. If you encounter the error above, please try checking in the PHP error_log for the respective user you attempted the import from. The PHP error_log will most likely return an error similar to the one below:

PHP Warning:  POST Content-Length of 108671420 bytes exceeds the limit of 57671680 bytes in Unknown on line 0

Workaround

To resolve this, you must increase the PhpMyAdmin upload limit. How to do this is mentioned in our article here:
