As plugins, themes, and WordPress itself, are constantly being updated, you are likely to encounter a problem with a plugin or your theme at some point. But it can sometimes be difficult to figure out which plugin (or theme) is causing the error. One way to do this is to deactivate all of your plugins, and then activate them one-by-one until you encounter the problem.
But doing this can break your site!
Deactivating plugins or your theme can impact on your site, causing disruptions for your users. So you don’t want to do this on a live site. Instead, we recommend using the Health Check plugin by The WordPress.org Community. This plugin can help you debug your site and determine whether the error is being caused by a plugin or theme. Plus it can do this without interrupting your live site, allowing visitors to continue using your site as they normally would.
Below we take a step-by-step look at how to use Health Check to debug your WordPress site.
Step 1: Install and activate the Health Check plugin
From your WordPress menu, goto Plugins –> Add New. Search for the Health Check plugin (make sure it is the correct one, by The WordPress.org Community). Install and activate the plugin.
Once installed, you’ll see a troubleshooting option next to each plugin on you Plugins page. (Clicking on any one of these links from your plugins page will enable troubleshooting mode.)
You’ll also find a Troubleshooting tab in your Site Health tool. Site Health is located in your Tools, but you should also be able to find a Site Health panel on your WordPress dashboard.
Step 2: Enable Troubleshooting Mode
In Troubleshooting Mode, users will still see and be able to use your live site. As you’re logged in, however, you will see the site in troubleshooting mode. This means that, for you only, the site has disabled all plugins and themes, and has reverted back to a default theme.
To enable this mode goto Tools –> Site Health –> Troubleshooting and click on Enable Troubleshooting Mode. Note that once enabled, you will either need to log out or disable this mode manually.
Step 3: Troubleshoot Your Site
After enabling Troubleshooting Mode, you’ll be redirected to a panel on your dashboard. From here, you can troubleshoot your site by enabling one plugin at a time, or by switching to a different theme.
If an error occurs as you are enabling plugins, you should see a notification appear in the Notice section. In this way, you can determine which plugin or theme is causing the issue on your site. If necessary, you can then contact the relevant plugin or theme developer to help resolve your issue.
Depending on the issue you had initially, you may need to navigate to the page with the problem to see if it is still happening. We recommend you open the problematic page in a new tab so you can easily enable plugins one at a time, and simply refresh the page to see if you still have the problem.
Step 4: Disable Troubleshooting Mode
Once you have determined where the error is coming from, remember to disable troubleshooting. You can do this by clicking on the Disable Troubleshooting Mode button in the Health Check panel. Your site will return to normal for yourself, and continue as before for your users.
