I updated my theme this morning and after doing so, the only thing that pops up on my blog site is: Fatal error: Call to undefined function get_custom_header() in/home/content/76/9248676/html/wp-content/themes/blaskan/functions.php on line393 and my blog is completely down.
I ended up switching to a basic theme for the time being so that viewers can access my content, but I would like to continue using my Blaskan theme. Anyone know how I can fix this?!! Could this be that I haven't updated to the most current version of WordPress yet??
