Do you have a recent backup you can restore from?

How do I find the backup in my web hosting service? Does it automatically back it up? I think I had a plug-in that would backup my files.

Hi im1217, you need to find in your theme all the functions "register_sidebar" and add "id" for it.

for example:

register_sidebar(
array(
'name' => 'sidebar',
'description' => '',
'before_widget' => '<div id="%1$s" class="side widget %2$s">',
'after_widget' => '</div>',
'before_title' => '<h3 class="widget-title">',
'after_title' => '</h3>'
)
)


had to changed like it:

register_sidebar(
array(
'id' => 'sidebar_1',
'name' => 'sidebar',
'description' => '',
'before_widget' => '<div id="%1$s" class="side widget %2$s">',
'after_widget' => '</div>',
'before_title' => '<h3 class="widget-title">',
'after_title' => '</h3>'
)
)

You can search for a relevant solution from google. there are you can find a very much proper answer.

It is because of the new WordPress version arrives in the market. So there may affect some plugin so that plugin not working properly.

One or 2 of your plugins may not be updated according to the latest WordPress 5.0. This will obviously give you error. Either deactivate that plugin or downgrade your Wordpress back to older version.
