Internal Server Error apache

  1. You might have edited your .htaccess file in Windows notepad or text editor. If you did use Windows text editor then it must have added some special chars in .htaccess file and that will lead to 500 internal server error. Never edit in Windows text editor.

Use notepad++ for editing .htaccess and .htpasswd files.

  1. second thing you should try is open your .htaccess file and put a # in front of BEGIN WordPress. Like this.

    # BEGIN WordPress
    

and there should be a line also. like this.

    # END WordPress

If you still have issues or you don’t understand then paste your .htaccess file content here in your question by editing it.
