Hi, I have a problem. After updating Wordpress, I can't log in to my site administration panel because I have the following errors:
Warning: Declaration of WP_Export_Installer_Skin::feedback($string) should be compatible with WP_Upgrader_Skin::feedback($string, ...$args) in /wp-content/themes/Workcafe/export/export.php on line 1009
Warning: Cannot modify header information - headers already sent by (output started at /wp-content/themes/Workcafe/export/export.php:1009) in /wp-includes/pluggable.php on line 1265
Warning: Cannot modify header information - headers already sent by (output started at /wp-content/themes/Workcafe/export/export.php:1009) in /wp-includes/pluggable.php on line 1268
This is probably because Themler has not been updated before. What can I do in this situation to enter the website's admin panel and update Themler?
