FYI:
One of my server is PHP 5.0.4, and after updating SQLyog to 5.23rc1, an error occured and couldn't connect with the server with SQLyogTunnel.php.
Until 5.17, there was no problem.
In my case, it was because the new tunneler was using “mysqli” setting.
(Still I'm not sure whether it is a problem of server, or SQLyog, or tunneler..)
Anyway, I changed the SQLyogTunnel.php:
from line 1524:
Code:
//if (extension_loaded('mysqli'))
//{
// define (“DB_EXTENSION”, “mysqli”);
//}
//else
if (extension_loaded('mysql'))
Then it started working.
It may be useful for someone as a minimal workaround….
