single post page broke with 18.1.0 update

Hi there,

Have you tried a conflict test?

This is likely caused by a conflict with another plugin.

How to test for conflicts

The best way to determine if the issue is being caused by a plugin is to:

1. Temporarily deactivate all plugins. You can do this manually or use a plugin to help (see below for tools).
2. Try to reproduce the problem. If the problem is resolved, it’s a plugin conflict. To figure out which plugin is causing the problem, continue to the next step.
3. Reactivate your other plugins one by one, testing after each, until you find the one causing conflict.

If this doesn’t help, you can try temporarily changing your theme as well to see if this is related.

Recommended tools to help with troubleshooting

* Meks Quick Plugin Disabler will remember what plugins you had active when you switch it back on.
* You can clone your site to a staging environment and perform tests without modifying your live site or impacting customers. Many hosts provide staging facilities, so it’s worth checking in with them. It’s also possible to do it using the free WP Staging plugin.
