phpMyAdmin is a fantastic tool for those of us using MySQL, Percona, and/or MariaDB. It’s been around for a long time and has many features that developers “just can’t live without”.
If you have run into the issue with phpMyAdmin displaying an “error message” at the top of the screen, that isn’t really an error message, but more to the effect of:
Error text: OK (rejected) It seems that the connection to server has been lost. Please check your network connectivity and server status.
You should probably do one or both of these:
1) Modify config.inc.php
$cfg['VersionCheck'] = false;
and/or
2) Make sure the PHP function curl_exec() is allowed for the PHP configuration for phpMyAdmin.
