Hi Andre,
I am also getting this error on a post:
Fatal error: Call to undefined function celestial_entry_meta() in /home/weldon8/public_html/wp-content/themes/celestial/content-aside.php on line 22
I am using a child theme of Celestial Reloaded 2.6.5.
Do I need to delete that function call like you told the other poster? Let me know what other information you might need! 🙂
Thanks!
