Webmail Error

[arazas]

Parse error: parse error, unexpected T_CONSTANT_ENCAPSED_STRING, expecting ',' or ';' in C:\Inetpub\vhosts\webmail\horde\login.php on line 46


When I open webmail for any domain it is giving above error, I have rebooted the machined, attempt to restart MySQL but this does not work. I have also reconfigured Plesk file securities but no luck.

Please help.
