A simple solution could be:
Adding a new plugin named "rewriteMyAdmin"
pass the following code:
$e = &$modx->Event;
switch ($e->name) {
case "OnWebPagePrerender":
$o = &$modx->documentOutput; // get a reference of the output
$o = str_replace("?phpMyAdmin=", "", $o);
break;
default :
return; // stop here - this is very important.
break;
}
Add your corresponding string after "?phpMyAdmin="
example: ?phpMyAdmin=LtsNms3Yvlnk6JRBjMLAoPd8Yh3
And highlight "OnWebPagePrerender"
Only use this if your site doesnt use any GET parameters, else get rid of the ? (questionmark) in the plugin str_replace
So far i could see Wayfinder is where these ?phpMyAdmin parameters apear
