"Add to your library" button gives error

The "Add to your library" button on work pages is giving me the error:

Choose a default source for adding books from other sites.
 Warning: include_once(inc_user_search_sources.php): failed to open stream: No such file or directory in /var/www/html/inc_librarylist.php on line 4 Warning: include_once(): Failed opening 'inc_user_search_sources.php' for inclusion (include_path='/var/www/html:.:/php/includes:/var/www/html/phpQuery/:/var/www/html/phpQuery/plugins/') in /var/www/html/inc_librarylist.php on line 4

The same sort of error message occurs today when I try to Add to Wishlist. Thanks, Warren

Same here.

same error for me for both the add to libary and add to wishlist

It's been three days now and I can't get past this error message to add to library (I know I can do it by searching, but that's slower).

Well you can always add via the Add Books tab ...

This should now be fixed. Let me know if you're still having trouble. Thanks!

Works here! Thanks!
