I’ve tried disabling and enabling third-party plugins and clearing the browser cache, it doesn’t help. Anyway, when you select 5 columns grid or 6 columns grid and click the next page selection arrow, I see broken page. The site (https://data.rborod.in/) has one more problem, it is veeery slow while the site https://boonhalo.com/ which is on the same server is much faster.
Website https://data.rborod.in/ has been backed up.
