Hi, I'm very new here and I hope anybody will understand my problem. I simply cannot connect to my mysql database via a php script, which is executed on my x10 host. I got an error page 500. Internal Server error. Of course, I've searched in the forum for a solution, but I didn't understand everything very well. You can be sure, that i used localhost as server name, cpname_dbname and cpname_user with correct password as login data for mysql_connect(). I guess, that there is also the firewall problem of x10. But I don't require a static ip address, because I thought the x10 firewall will allow any requests from its users. Thanks for help and sorry for my English. :/
