Daily tip not updating since upgraded to WordPress 4.9.6

I am webmaster to this site.
Love your plug-in, did just what I needed to do
Was forced to upgrade from my web hosting co because of security issues
now the tips are not updating which is a big part of daily traffic to the site.
was updating on Internet explorer only, now seems to be stuck on all browsers/platforms.
THe database is updated through the end of july so the data is there, just not posting on the site
please advise

thanks
