I cannot login to my website due to a mistake in the fitness calculator plugin: PHP Warning: Cannot modify header information – headers already sent by (output started at /var/www/iformsupport.dk/public_html/wp-content/plugins/fitness-calculators/fitness-calculators-plugin.php:42) in /var/www/iformsupport.dk/public_html/wp-login.php on line 400.
When will the issue be solved?
Best regards
Thomas
