The same thing has happened.
But the error to me is a little different.
Notice: register_sidebar was called incorrectly. No id was set in the arguments array for the ” ” sidebar. Defaulting to ” “. Manually set the id to ” ” to silence this notice and keep existing sidebar content. Please see Debugging in WordPress for more information. (This message was added in version 4.2.0.) in /home/—/—/public_html/wp/wp-includes/functions.php on line 3560
” ” nothing is written.
Perplexed.
