Reply To: Home page won't save and 404 has weird code at the top

Here is the code at the top of the 404 page:

Warning: array_unique() expects parameter 1 to be array, string given in /home/owcpanel/public_html/wp-includes/post-template.php on line 682

Warning: join(): Invalid arguments passed in /home/owcpanel/public_html/wp-includes/post-template.php on line 499
class=””>

I’ve tried re-uploading the wp-includes folder from a fresh install of wordpress but no luck. The biggest issue is not being able to save the home page.
