 Hi,

 all the best for 2021.

 When I try to to edit a post or page I get a full white blank page with
 the following message:

    Notice: ob_end_flush(): failed to delete and flush buffer. No buffer to
 delete or flush in /wp-content/themes/theritchers-theme/library/pew.php on
 line 39

 We have the latest wordpress version and gutenberg.

 the web is www.onlytherichters.com

 Hi @voodoopol and welcome to Trac!

 The support forums would be better than Trac when asking for help with
 themes, plugins and/or individual site support.

 A number of topics have been created
 [https://wordpress.org/search/ob_end_flush+failed+to+delete+and+flush+buffer?in=support_forums
 about this error in plugins].

 At least one of those plugins was fixed with an `if(ob_get_length())`
 conditional:
 - [https://wordpress.org/support/topic/php-notice-ob_end_flush-failed-to-
 delete-and-flush-buffer/#post-9156760 user edit]
 - [https://github.com/sparanoid/relative-
 url/commit/e42d10ab43593aa303716373c617b4c9da509aa8?branch=e42d10ab43593aa303716373c617b4c9da509aa8&diff=unified
 official change]

 **Before editing** the theme's pew.php file, though, make sure you have
 another theme installed (any other themes would be inactive). If the file
 change includes a simple syntax error, you may need the other theme as an
 automatic fallback.
