Cannot read properties of undefined

Hello @tesla369963

Thank you for reaching out to us. Your site may have third-party themes or plugins that may be conflicting with the AMP plugin, causing one of the features of AMP to fail. I will recommend doing self debugging using health check and troubleshooting plugin. Here are steps you can follow.

1. Install and activate the Health Check & Troubleshooting plugin.
2. Navigate to Tools > Site Health > Troubleshooting.
3. Enable troubleshooting mode
4. Visit Appearance-> Themes -> Activate Your theme
5. Visit Plugins-> Installed plugins -> Activate AMP plugin
6. Visit plugin -> installed plugins and activate one of the plugin (only one at a time) which was active on your site
7. Check AMP Page version of your page which caused the issue
8. Do you found that issue?
9. if yes, then you found culprit report back to us, or check that plugins settings
10. if not, continue from step 6

We hope this helps!
