This has started for me too after Elementor upgrade.
Jazakallah Khair. That worked perfect.
Hi
I cannot upgrade the sliders as the admin page is also coming up with the same error and I cannot login.
Warning: Cannot modify header information – headers already sent by (output started at /homepages/43/d698830353/htdocs/app699534317/wp-content/themes/businesso/core-functions/option-panel/businesso-option-setting.php:228) in /homepages/43/d698830353/htdocs/app699534317/wp-includes/pluggable.php on line 1216
I am using 1and1 managed wordpress.
Any help would be appreciated.
Regards
