 * When activating WP Super Cache, I get the following error in my server error 
   logs, when html pages, that reside in the same directory as wordpress are called(
   note: but not when any pages within wp are called!).
 * PHP Fatal error: Unknown: Cannot use output buffering in output buffering display
   handlers in Unknown on line 0
 * Example:
    Wordpress install on mydomain.com in directory /mydomain
 * html page, that creates this error
    mydomain.com/sub/index.html in /mydomain/
   sub/
 * Theme Twenty Ten
 * I tried php and mod_rewrite. Both create this problem.
 * Any ideas?
    Many Thanks in advance, Sylvia
