This is halfway down the home page here, where it shows ALL and BLOG:http://infotechdesign.review/
It loads initially with the home page, but if you click the BLOG category (which the displayed article is in)...the page goes blank. Nothing showing at all in Apache error_log. I was having this problem with other categories with no published articles, so I removed them from the module categories, leaving "All Categories" and "BLOG" and nothing else. But I still get the blank page.
I also turned the Joomla Debug system on (which shows diagnostic info on the bottom of the home page), and the page is still completely blank when I click "BLOG".
access_log shows this AJAX command, but it gets a good return code 200:
"GET /?ajaxload=true&limitstart=6&catid=48&count=6 HTTP/1.0" 200 355761 "http://infotechdesign.review/" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_2) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/62.0.3202.94 Safari/537.36"
Any ideas? Running PHP 7.1 (I was trying with 7.0), latest Joomla 3.8.2.
