AMP error: The text inside tag ‘style amp-custom’ contains ‘CSS !important’

I don’t see !important CSS on the page.

Remote debugging doesn’t seem to be enabled.

Please also paste the code section which contains !important.

Thanks @spacetime for the quick reply.
Yes, even I don’t see the !important code but the AMP validator Chrome plugin reports it. When the validator website, in fact, says ‘Pass’

Currently I don’t have anything set up in ad inserter and still, it throws in that error. If I deactivate it then everything works.

Regarding the ‘Remote Debugging’ just I have to enable it? is there any security issues if I enable it? Please do let me know.

Well, I need to reproduce/see the issue. Otherwise I can’t suggest solution.

Maybe you are logged in and admin toolbar is shown (some menu items contain few properties with !important – nothing to worry about).
Try to log out and check again.

Remote debugging: enables other people using url parameters to see your pages with debugging data: debugger widget, labeled blocks, positions for automatic insertion, labeled tags and processing log. For logged in administrators debugging is always enabled.

Enable this option to allow other people to see debugging data in order to help you to diagnose issues with Ad Inserter.

If I logout from my WordPress account the extension shows an error saying my AMP validator not connected to internet (something like that). However, on the validation website, it shows ‘PASS’ status.

So now, I have added the settings in ad inserter for adding the ads and configured everything as I need. Still the status same as above.

I have enabled remote debugging, so kindly check what could be wrong.

Can you pease try this version:

@spacetime Wonderful! it worked!
I see the green tick!

When I installed the version back, the all my ad code left as it was before except the header code which was deleted, (google documentation says header code required). But my ads working without any code in the header. So left it as it is.

Thank you very much for addressing my issue quickly!

Great!
