.htaccess diverse Fehler!?

Hallo,
habe eben einmal meine htaccess mit lyxx.com (syntax) geprüft.
Ergebnis: Lyxx found 28 problems in the code segment(s) below.

Leider habe ich kaum bis keine Kenntnisse um die Fehler selbst einschätzen zu können. (In Form von Dramatisch!? / Kein Problem!?)
Ich arbeite mit Wordpress und hier mit einem Plugin zum cachen der Webseite. Das Plugin heißt: WP Super Cache und wirft folgenede Fehler aus:
