Hi,
First, please make sure you do the AMP config like we said on the documentation here
After that, check again your amp page via https://search.google.com/test/amp
If it has any error, continue try deactivate all plugins ( except plugins come from the theme ) and try it again. If it works, let's enable each plugin to check what's plugin caused this issue.
Best Regards,
