Couldn’t edit poll due to class-wp-block-parser.php on line 417 (wp 5.3.2)

After last update to WP 5.3.2, the error messages below are appearing at the top of the page:

Warning: preg_match() expects parameter 2 to be string, array given in /home/dir123/public_html/xpto.com.br/wp-includes/class-wp-block-parser.php on line 417

Warning: strlen() expects parameter 1 to be string, array given in /home/dir123/public_html/xpto.com.br/wp-includes/class-wp-block-parser.php on line 489

I have the same issue

I will probably wait for WP to fix it and waut fir the final verdict.

The offending line might be polls-manager.php, line 146.

Can try replace:
$polla_answers_new = isset($_POST['polla_answers_new']) ? wp_kses_post( $_POST['polla_answers_new'] ) : null;

With:
$polla_answers_new = isset($_POST['polla_answers_new']) ? $_POST['polla_answers_new'] : null;

With replacement editing works correctly.

Thanks, I have fixed it https://github.com/lesterchan/wp-polls/commit/2a6cf766dc9cdffb4cfcd6ab66be72a22efbef84. Will release it after the holidays.

Hey @gamerz, thanks for the fix. Can you update the plugin version here? it’s still at 2.75.3

Released the fix.
