Xplorer 5.0 – "Exception thrown within the exception handler!"

Hello, I have just installed the PHP addon from RNXtras and after that, the Xplorer 5.0 addon by SuperPoussin without a hitch but upon trying to access the addon page all I get is the below error messages:

Exception thrown within the exception handler! Message was: Cannot find plugin text for type log in /c/webroot/xplorer/core/classes/class.ConfService.php on line 164 #0 /c/webroot/xplorer/core/classes/class.ConfService.php(184): ConfService->initUniquePluginImplInst('LOG_DRIVER', 'log')

#6 [internal function]: AJXP_XMLWriter::catchException(Object(Exception))
#7 {main}

Does anyone recognise this? I've tried to find an answer in these forums but so far I've been unsuccessful.

Thanks
