Do you mean that the searc hangs at that point? I can see that problem, the server returns an error, without an error message, so I'm not sure what exactly the cause is.
Can you please check the back-end details? I'm not able to log-in with them. Also, if you could add temporary FTP as well, it would probably help a lot, as server side errors are almost impossible to debug without accessing the code.Best,
