When I try to login or look at my blog I see:
Fatal error: Call to undefined function add_shortcode() in /mnt/w0711/d09/s27/b0275c7c/www/ldscoloringpages.net/WPblog/wp-content/themes/veryplaintxt/functions.php on line 693
I am sure this is all my own stupid fault because I forgot to disable the theme before I deleted the old theme files and uploaded the new ones.
What do I do now?
By the way, I still need to upgrade to the latest version of WordPress. I am considering doing an upgrade to attempt to fix this problem, but I cannot make a backup or disable my plug-ins since I cannot login.
Thanks in advance.
