 Hello,

 When I open my blog, I get the following error message:
 {{{
 Warning: Illegal string offset 'custom_css_post_id' in /.../wp-
 includes/theme.php on line 1063
 }}}

 In the dashboard I see the following message:
 {{{
 ...ng offset 'nav_menu_locations' in /.../wp-includes/theme.php on line
 1063


 Warning: Cannot modify header information - headers already sent by
 (output started at /.../wp-includes/theme.php:1063) in /.../wp-
 includes/functions.php on line 6362
 }}}

 Line 1063 is `$mods[ $name ] = apply_filters( "pre_set_theme_mod_{$name}",
 $value, $old_value );`

 I have tried: uploading wordpress again with ftp, clearing caches,
 reinstalling the twenty twenty one theme, deactivated plugins, uploading
 the theme.php file again.
 I don't see this bug when I activate other themes.

 The forum thread is: https://wordpress.org/support/topic/theme-
 down/page/2/#post-14525964

 Is there anything else I can do?

 Kind regards,

 Karen

Comment (by sabernhardt):

 @karenaug Hi and welcome to Trac!

 Your site still uses Twenty Twenty-One, and the custom CSS is included
 properly now. Were you able to fix it somehow?

 I received similar errors with Twenty Twenty (and possibly Twenty Nineteen
 as well) around the time you opened the support topic and this ticket. I
 think the errors occurred immediately after activating a plugin, though
 you said that was not the case when you had trouble. (Because my site was
 a local development site, on WP5.8-alpha, I replaced it entirely.)
