Got error 500 with Filenames containing points

[ephigenie]

To be honest judging from your default-error.log it seems as if there's maybe also a problem with your typo3 rewrite rules ?

Premature end of script headers points to a failure on executing the file ( syntax error or something like that ? ) ...

Please make a test and remove your rewrite rules completely, then place a simple test.test.test.php file with <? phpinfo(); ?> in it in your directory root and try to open it via webbrowser. Send the log then pls as well.
