Thread:Project:Support desk/Fatal Error after installation

I receive the below error after installation of wiki version 1.22.4

Fatal error: Call to a member function checkTitleEncoding on a non-object in C:\Program Files\Apache Software Foundation\Apache2.2\htdocs\wiki\includes\db\DatabaseOracle.php on line 1158

In Apache error.log this message shows up

[Wed Mar 19 13:27:09 2014] [warn] [client 10.105.140.107] mod_fcgid: stderr: PHP Fatal error: Call to a member function checkTitleEncoding on a non-object in C:\\Program Files\\Apache Software Foundation\\Apache2.2\\htdocs\\wiki\\includes\\db\\DatabaseOracle.php on line 1158

PHP Version 5.4.26 Apache Version 2.2.21 mod_fcgid Version 2.3.6

Any idea where to search?
