language problem

[jharvey]

I am new in making website..I made a mistake when I changed the language to ENLISH only..

 

but there is an error when I try to open the web

 

Warning: main(includes/languages/.php) [function.main]: failed to open stream: No such file or directory in /homepages/23/d238298060/htdocs/includes/application_top.php on line 288

 

Fatal error: main() [function.require]: Failed opening required 'includes/languages/.php' (include_path='.:/usr/lib/php') in /homepages/23/d238298060/htdocs/includes/application_top.php on line 288

 

What should I do to fix it? thanks a lot.
