Yoday I have a mistake.
I change in > setting>wordpress url > and here add the extention index.php.
Yesterday was nothing here, only the path without index.html
now I cant login to my control panel,.
you can see here that in fact the css file can't be found.
when I try to login just can see a error page, 404, page not found.
How can restart the default setting without the "index.php" extention that I put inside the setting option?
