Error when trying to make a new post

Function ‘mywebsite_posted_on()’ doesn’t exist. try deleting that line in content.php. it’s line 24. you can see full path and line where it is if you read bottom line on your site.

While that did take the error away, it messed up the entire page :|. Something I should mention is that “mywebsite” is the name of my theme… It’s my theme :)… It’s a part of content.php

for example:

<?php twentyeleven_posted_on(); ?>

^^That’s straight off of twentyeleven theme, content.php, line 24.

These seems to be a theme error, check for updates, to make sure you can activate the default theme to see if it displays the posts (if you are not using custom posts).

do you have this in your functions.php

if ( ! function_exists( 'mywebsite_posted_on' ) ) :
/**
 * Prints HTML with meta information for the current post-date/time and author.
 * Create your own twentyeleven_posted_on to override in a child theme
 *
 * @since Twenty Eleven 1.0
 */
function mywebsite_posted_on() {
	printf( __( '<span class="sep">Posted on </span><a href="%1$s" title="%2$s" rel="bookmark"><time class="entry-date" datetime="%3$s" pubdate>%4$s</time></a><span class="by-author"> <span class="sep"> by </span> <span class="author vcard"><a class="url fn n" href="%5$s" title="%6$s" rel="author">%7$s</a></span></span>', 'mywebsite' ),
		esc_url( get_permalink() ),
		esc_attr( get_the_time() ),
		esc_attr( get_the_date( 'c' ) ),
		esc_html( get_the_date() ),
		esc_url( get_author_posts_url( get_the_author_meta( 'ID' ) ) ),
		esc_attr( sprintf( __( 'View all posts by %s', 'mywebsite' ), get_the_author() ) ),
		get_the_author()
	);
}
endif;
