debug wp-cli errors runcloud can be frustrating when WP-CLI crashes silently. Here’s how to automatically identify problematic plugins.

When WP-CLI crashes because of a plugin, you don’t know which one is causing the issue?

This guide walks you through how to use the debug-wp-cli.sh script, a bash script specifically crafted for isolating and identifying problematic plugins on RunCloud servers.

When WP-CLI Crashes Because of a Plugin

One common scenario is when WP CLI crashes with a PHP fatal error. You may receive an error message that points to a specific file or line, which might not always lead you directly to the plugin causing the issue. This script helps you systematically narrow down the problem by testing each plugin in isolation.

How the debug wp-cli errors runcloud Script Works

The script works as follows:

  • Takes a –site= argument, validates that the site exists in the RunCloud directory structure (/home/runcloud/webapps/).
  • Detects the site owner (using the stat command) and runs WP-CLI as that user to ensure the script behaves identically.
  • Gathers a list of all plugins currently active on the site using wp plugin list --field=name.
  • For each plugin, it temporarily disables that plugin using the --skip-plugins=$plugin option with WP-CLI and runs a simple evaluation script (echo test;) to see if the error persists.
  • If disabling the plugin allows WP-CLI to run without errors, then the isolated plugin is identified as causing the issue.
  • The script prompts the user to confirm whether they would like to deactivate that suspected problematic plugin.

If all plugins are tested and none of them cause the error to disappear, the script concludes that no single plugin triggered the issue.

Running the Script

To run the script:

  • Download the script using wget https://raw.githubusercontent.com/codetot-web/runcloud-bash-scripts/refs/heads/main/debug-wp-cli.sh.
  • Make the script executable with chmod +x debug-wp-cli.sh.
  • Run the script with ./debug-wp-cli.sh --site=sitename, replacing sitename with the name of your site.

Interpreting the Results

The output will indicate which plugin, if any, is causing WP-CLI to crash. If a problematic plugin is identified, you’ll be prompted to deactivate it to resolve the issue. If no single plugin causes the error, you can take manual steps as described in the next section.

Manual Alternative (without the script)

Without using the script, here’s how you can manually identify a problematic plugin:

  • Disable Plugins: One-by-one, disable all plugins. Make sure to switch your site to debug mode and clear cache after each step.
  • Check for Errors: After deactivating each plugin, test WP-CLI again. Look for any changes in behavior. If the error disappears when a particular plugin is deactivated, that’s likely the culprit.
  • Re-enable Plugins: Once identified, re-enable all other plugins and try to locate if another one interacts poorly with the suspected problematic plugin.

Important Notes

This script focuses on isolating plugins that interfere with WP-CLI by causing a PHP fatal error. It should not be used for debugging memory leaks, performance issues, or other types of problems unrelated to plugin conflicts.

Note: Always ensure you have a backup before making changes to your site’s configuration or running diagnostic scripts like this one.
