Hi all, Horde webmail interface begins giving us the following error all of a sudden for all our domain names hosted in our dedicated server. Warning: main(php_ver_checker.php): failed to open stream: No such file or directory in C:\Inetpub\vhosts\webmail\horde\Index.php on line 2 Warning: main(): Failed opening 'php_ver_checker.php' for inclusion (include_path='.;./includes;./pear') in C:\Inetpub\vhosts\webmail\horde\Index.php on line 2 I searched the forum all day, read many problems and suggestions related to horde, but I am kind of lost. Would anybody please give me some advice, pointers on the issue? Thanks.
