Dear Friend,
My wordpress update to 5.8 today, but when I edit my website, it show the below warning words at the head in everywhere of the dashboard.
Warning: Cannot modify header information – headers already sent by (output started at /home/customer/www/v2.xxxxx.com/public_html/wp-content/plugins/lingotek-translation/admin/filters-post.php:1) in /home/customer/www/v2.xxxxx.com/public_html/wp-includes/functions.php on line 6584
And when I do import and output in the dashboard, it turn to a page full with words, it also start with the above warning.
When I setting the language it turns to an empty page only with the same warning.
That’s a big problem. Can you help me? Thanks.
Best regards,
Kevin
