Can anyone assist? I am getting the messages below when I try to access the dashboard of my site gallerycy.com It has happened since WP updated automatically to 4.9.2
Warning: preg_match(): Compilation failed: unrecognized character after (?< at offset 4 in /web1/user53852/website/wp-includes/wp-db.php on line 1657
Warning: Cannot modify header information – headers already sent by (output started at /web1/user53852/website/wp-includes/wp-db.php:1657) in /web1/user53852/website/wp-includes/pluggable.php on line 1216
Assistance would be much appreciated.
