Can't login in on admin page

Follow this guide to change your password directly in the database: https://codex.www.ads-software.com/Resetting_Your_Password#Through_phpMyAdmin

Along the way, you’ll see what your username is too.

You’ll find phpMyAdmin in your hosting account’s control panel.

It doesn’t let me change it like that it says :

“Notice in ./libraries/insert_edit.lib.php#1753
Undefined index: submit_type

Backtrace

./tbl_replace.php#73: PMA_getParamsForUpdateOrInsert()”

You’ll have to contact your hosting provider. That’s an issue with their phpMyAdmin installation.
