Maybe go to "php/mod_insertWmcIntoDb.php" and check line 32

$mapObject = $json->decode($_REQUEST["mapObject"]);

This may be the source of all evil.

Maybe try to take a look at $mapObject via var_dump.

If you have PHP > 5.2 you might want to use the php-native JSON function 
json_decode (or is it decode_json?).

Please let us know if you are inding sth. significant

Thanks for your time
