When I implemented the latest version of Wordpress, Myriad theme no longer worked. This is what appeared for my website url and for the wordpress dashboard:
Fatal error: Call to undefined function get_post_format_slugs() in /home/debrahur/public_html/wp-includes/theme.php on line 1273
I talked to my web provider and they said it looks like Myriad won't work with the upgraded wordpress. They are trying to re-implement the former version of Wordpress so I can at least have my site and admin. page working again.
What am I to do?
