PhpMyAdmin Error – incorrect format parameter might appear on multiple hosting platforms like shared hosting, VPS, localhost, or Dedicated Server.

This article will show you how to resolve the problem and fix this phpMyAdmin Error.

What is the cause of this error?

Sometimes, we import the database into MySQL server through PHPMyadmin, incorrect format parameter errors may appear.

PhpMyAdmin Error incorrect format parameter might appear due to multiple reasons such as:

  • Execution of a script exceeding the defined maximum execution time on the server.
  • Parsing of requested input data exceeds the defined maximum input parsing time.
  • Script needing operating memory higher than the one defined in memory limit.
  • The size of post data is higher than the defined maximum post data size.

To be clearer, I have the same problem and try to find php.ini to edit. But it does not work, when I import MySQL file via phpMyAdmin, I was getting this error: Incorrect Format Parameter. Then I found the cause: I was modifying the wrong php.ini!

Where does MAMP keep its php.ini?

Depending on your version of PHP, there will be 2 php.ini files in MAMP (in this example is PHP 7.2.10):


The file you have to edit is in MAMP Pro and uses the php.ini file every time it starts up:
Edit File > Edit Templates > PHP 7.2.2 php.ini
Restart MAMP Pro
Your changes should stick.
Or you can go by:
MAMP-> bin-> php-> php(your php version)-> conf-> php.ini

If you are not sure where is php.ini, just create a phpinfo.php file at your localhost root. Put this <?PHP phpinfo(); ?> within it, run that from your browser. Look for the value Loaded Configuration File.

This tells you which php.ini file PHP is using in the context of the webserver.

Edit MAMP php.ini
