It looks like the issue here is that you are using a CDN which is rewriting many of your URLs in the source code of your site to use `stackpathdns.com` for example: `https://730009-2439504-raikfcquaxqncofqfm.stackpathdns.com/`. * This is causing the validation error because the URL is different what is being expected. You will need to address this to clear the AMP validation error you are seeing. This will need to be done via your CDN settings which falls out of the scope of Web Stories support. * Please do let us know if you you fix this and are still experiencing issues with your Web Stories and we can look further into this for you. * Thread Starter [csc721](https://wordpress.org/support/users/csc721/) * (@csc721) * [4 years, 6 months ago](https://wordpress.org/support/topic/compatibility-issue-62/#post-15494053) * Hi [@adamdunnage](https://wordpress.org/support/users/adamdunnage/), * Can you give me the info regarding CDN settings?

I can see you have several active plugins. There could be a plugin conflict causing this so if possible would you be able to manually deactivate plugins one by one and between each run your story through the [AMP validator](https://search.google.com/test/amp/). For best results, use an [incognito window](https://imgur.com/ALzgiHp) when performing the AMP validation to avoid any cached results. * If at any point the story returns as valid then it means that the plugin previously deactivated is causing a conflict. Let me know how you get on with this and if you have any further questions. * Thread Starter [csc721](https://wordpress.org/support/users/csc721/) * (@csc721) * [4 years, 5 months ago](https://wordpress.org/support/topic/compatibility-issue-62/#post-15578446) * [@adamdunnage](https://wordpress.org/support/users/adamdunnage/) Can you suggest me a plugin for detecting plugin conflicts? That will help me a lot. Thanks. * [Adam Dunnage](https://wordpress.org/support/users/adamdunnage/) * (@adamdunnage) * [4 years, 5 months ago](https://wordpress.org/support/topic/compatibility-issue-62/#post-15578517) * [@csc721](https://wordpress.org/support/users/csc721/) Unfortunately I cannot recommend a plugin that will do this. The reason for this is that plugins with this functionality only replicate the plugins being deactivated on the backend and as a result the AMP results are not refreshed. * This means that you will have to manually deactivate these plugins for the AMP validation results to refresh when running them through the validation tool.
