Some blocks in Gutenberg like tables, quotes, separator benefit from structural styles (margin, padding, border etc…)
They are applied visually only in the editor (back-end) but not on the front-end to avoid the risk of conflicts with the styles wanted in the theme.
If you want to display them on front to have a base to work with, in this case, you can add support for wp-block-styles.
You can consult Matias Ventura’s tickets to keep you informed about Gutenberg developments : https://make.ww.wp.xz.cn/core/2018/06/05/whats-new-in-gutenberg-5th-june/
Works perfectly thank you very much !
Hi, I join your question, I have exactly the same need to use custom permalinks only for pages
In single-category-permalink.php change on line 72
usort( $cats, ‘_usort_terms_by_ID’ ); // order by ID
by
usort( $cats, ‘wp_list_sort’ ); // order by ID
seems to solve this notice
