使用页面或发布自定义模板时，the_content突然不显示内容

I had to fall back to an earlier version of the site. It went right back to working as intended. I updated the woocommerce plug-in. All still worked. Suspect the Jetpack plug-in causing the trouble but can't prove it. (I deactivated it when troubleshooting but that didn't fix problem.) I just got email from GoDaddy saying they had detected the old version of Jetpack is causing a fatal error. I haven't seen an error yet but I believe them. Deactivated it and will probably uninstall it if I can use other plug-ins for the same features.

As I work to restore the posts I added in the last couple days, I'll make note if anything stops working and will report it here in case anyone else ever hits the same problem. TY.

the_content and the_date in post and page template files not working

All was well. Custom page and post template worked as intended on WordPress site for months. Only used these custom templates for photo albums and blog. (Using child theme of Storefront theme. All store related pages use WooCommerce templates, unaltered.)

Suddenly, yesterday, custom page and post templates stopped displaying the content and the date. I had added products to WooCommerce but no changes to code. Added demo products in past with no problem.

When I saw the problem, I turned all plug-ins off, including WooCommerce - malfunction continues. I just can't figure out why code that worked suddenly refused to pick up the_content and date, especially when I had made no changes to the templates that morning.

• Turned off plug-ins.
• Looked at functions.php to see if anything affected the_content. Didn't see anything and custom functions file is the same as when the_content worked.
• Pulled up pages and posts in Chrome - no errors detected, though it doesn't show the_content being called.

If I must, I'll restore a version of the site from days ago to see if the problem clears up but would rather avoid that if possible.

Expect content and date to show as they did right up till yesterday morning. Instead, they don't. I'm baffled.
