Yesterday, i have a problem with my phpMyAdmin in my cpanel.
I can't export and import my DB through Cpanel phpMyAdmin.

It always shows like below :

export.php: Missing parameter: what (FAQ 2.8)
export.php: Missing parameter: export_type (FAQ 2.8)

So after searching a lot in google, my friend found that the issue is not in the phpMyAdmin but in the cpanel php.ini

So how to fixed that ?
please kindly to take a look how to solved this issue below :

These errors were occurring because the values specified in WHM -> Tweak Settings for:
-PHP Max Post Size for cPanel PHP in Megabytes (default 55M with a maximum value of 2047M)
-PHP Max Upload Size for cPanel PHP in Megabytes (default 50M with a maximum value of 2047M)

it did not have the trailing "M" -- for example, it was  "50" instead of "50M".. This meant that the max post size and max upload size were 50 bytes instead of 50 megabytes

Hopefully this also can help others sysadmin if they meet this issue :)
