Version 1.0.1: Uncaught Error: Class ‘AMP_Theme_Support’

@joewa1980 Would you please try uninstalling AMP and re-installing it?

It could be that there was a deployment problem with the plugin.

@westonruter Thanks, but we’ve tried that on the two sites we’re running it on. Deleted, then re-downloaded, re-installed and re-activated… same issue.

What version of PHP are you running? What is your server stack (Linux, Nginx, etc)?

There is an autoloader that should be loading the AMP_Theme_Support class as can be found here: https://github.com/ampproject/amp-wp/blob/96b194da2f63234f37748e753f0434614983a2dc/amp.php#L116-L117

You can see that AMP_Theme_Support is referenced in the autoloader file: https://github.com/ampproject/amp-wp/blob/96b194da2f63234f37748e753f0434614983a2dc/includes/class-amp-autoloader.php#L33

So all of this code should have run far before the line in question here: https://github.com/ampproject/amp-wp/blob/96b194da2f63234f37748e753f0434614983a2dc/amp.php#L567

These sites are both running PHP 7.2 on CentOS 6.x

I am not sure where to go from here. Do you have this running on a test environment you can give me access to for debugging?

Same issue…. I got the following error after updatating the plugin to the latest version.

Fatal error: Uncaught Error: Call to undefined function is_amp_endpoint() in /home/mysite/public_html/……..

The function is defined in the plugin. What is the stack trace?

@joewa1980 Were you able to overcome the issue?

No, we disabled the plugin and haven’t gone back to troubleshoot it. Ideally we’d like to use it though!
