Title: Error when showing AMP version Last modified: December 2, 2020 --- # Error when showing AMP version * Resolved [MartijnAtWordPress](https://wordpress.org/support/users/martijnatwordpress/) * (@martijnatwordpress) * [5 years, 8 months ago](https://wordpress.org/support/topic/error-when-showing-amp-version/) * Hi, * Hope somebody can help/ advise me on the following issues. * **PROBLEM:** * AMP doesn’t work correctly anymore. On mobile, it doesn’t pick up the AMP version automatically. * When I enforce the setting “Redirect mobile visitors to AMP” (Which should not be necessary), it still shows some issues when opening the AMP version. * _Note: AMP is only enabled on posts within the category “Hotel News” and “Travel News”._ * **ISSUE 1: Error message when visiting AMP page** * _EXAMPLE:_ When clicking on an AMP URL within Google Mobile Search, it shows first the following message “Sorry this page is not valid AMP HTML”, before it is redirected to the AMP version. * Please see an example video of the situation: [https://test123456.nl/test-2/](https://test123456.nl/test-2/) * PLEASE NOTE: When checking the AMP version via [https://search.google.com/test/amp](https://search.google.com/test/amp), The page is valid and has no errors. – Example AMP version for mobile: [https://test123456.nl/amp-version](https://test123456.nl/amp-version)( Desktop version: [https://test123456.nl/non-amp-version](https://test123456.nl/non-amp-version)) * _NOTE: to reproduce the exact issue can be difficult since:_ 1) The outcome differs (sometimes there is no error message) 2) Sometimes the URL is visible as an AMP and sometimes as NON-AMP version within Goggle Mobile search (See issue 2) * **ISSUE 2: The same URL not showing as AMP in Search** * The same day the URL can be visible within mobile search as AMP and then as NON- AMP page. It somehow switches between AMP and NON-AMP. * Please see the example: [https://test123456.nl/test-2/](https://test123456.nl/test-2/) * I hope I explained my case well. * I am looking forward to hearing from you. * Kind regards, Martijn - This topic was modified 5 years, 8 months ago by [MartijnAtWordPress](https://wordpress.org/support/users/martijnatwordpress/).

Do we have to reinstall/ configure the AMP plugin, so it picks up the “new HTTPS URL”? Or is there another way? * Kind regards, Martijn * Plugin Support [Milind More](https://wordpress.org/support/users/milindmore22/) * (@milindmore22) * [5 years, 8 months ago](https://wordpress.org/support/topic/error-when-showing-amp-version/#post-13745061) * No, you don’t need to reinstall the plugin, this might be because of the HTML minification feature you have enabled. * [data1online](https://wordpress.org/support/users/data1online/) * (@data1online) * [5 years, 8 months ago](https://wordpress.org/support/topic/error-when-showing-amp-version/#post-13745439) * Dear Milind, Thanks for pointing that out. I also speak on behalf of martijnatwordpress and wonder how I can influence the link in the amp by turning off minification( cf / ao / rocket). If I turn off all minification, would it automatically generate the new https protocol link? because then I can only turn it on and off? Doesn’t it seem to me that there must be a way to be able to access this manually outside of the minification? * [data1online](https://wordpress.org/support/users/data1online/) * (@data1online) * [5 years, 8 months ago](https://wordpress.org/support/topic/error-when-showing-amp-version/#post-13745672) * > Your amphtml link (screenshot) also references your URL without any scheme/ > protocol. it’s recommended to use https * How can we provide a protocol for these links If the links are generated automatically? * Plugin Support [Milind More](https://wordpress.org/support/users/milindmore22/) * (@milindmore22) * [5 years, 8 months ago](https://wordpress.org/support/topic/error-when-showing-amp-version/#post-13746780) * Hi [@data1online](https://wordpress.org/support/users/data1online/), * Check if you can add an exception for the rel=”amphtml” while doing HTML minification. * Also please check [amp_get_permalink](https://amp-wp.org/reference/hook/amp_get_permalink/) filter. * It will be very helpful if you share site health information via [this](https://docs.google.com/forms/d/1JTQmphDlk9YgHpDoFRbHXpkDqv8-QmzTT7MDR4AstyQ/) form so we can understand your setup better and provide better assistance. - This reply was modified 5 years, 8 months ago by [Milind More](https://wordpress.org/support/users/milindmore22/). * Thread Starter [MartijnAtWordPress](https://wordpress.org/support/users/martijnatwordpress/) * (@martijnatwordpress) * [5 years, 8 months ago](https://wordpress.org/support/topic/error-when-showing-amp-version/#post-13748535) * Hi [@milindmore22](https://wordpress.org/support/users/milindmore22/), I just filled in the form with the site health information. * Plugin Support [Milind More](https://wordpress.org/support/users/milindmore22/) * (@milindmore22) * [5 years, 8 months ago](https://wordpress.org/support/topic/error-when-showing-amp-version/#post-13754936) * Hello [@martijnatwordpress](https://wordpress.org/support/users/martijnatwordpress/) * Thanks for the info, I’m unable to reproduce the same issue from my side. Can you try to check whether the same issue arises when you activate plugins one by one following the steps below: 1. Install and activate the [Health Check & Troubleshooting plugin](https://wordpress.org/plugins/health-check/). 2. Navigate to Tools > Site Health > Troubleshooting. 3. Enable trouble shooting mode 4. Visit plugin -> installed plugins and activate them one by one and check which plugin is causing issue * You can exit troubleshooting mode afterward. * Thread Starter [MartijnAtWordPress](https://wordpress.org/support/users/martijnatwordpress/) * (@martijnatwordpress) * [5 years, 8 months ago](https://wordpress.org/support/topic/error-when-showing-amp-version/#post-13754976) * Hi [@milindmore22](https://wordpress.org/support/users/milindmore22/), * Hope you had a good weekend. * **– Question regarding:** _“Check if you can add an exception for the rel=”amphtml” while doing HTML minification”_ Where can we add this exception? * **– Regarding: ** _“Also please check amp\_get\_permalink filter”_ Please see [https://pastebin.com/D1wSxm00](https://pastebin.com/D1wSxm00).

How can we refresh those URL’s so all URLs convert to https inside the code, can Avada theme blocking something? * I cannot find a way to make an exception of “rel=”amphtml”, only files can be excepted in Autoptimize and Cloudflare does not show me an option either. * [Optimizing Matters](https://wordpress.org/support/users/optimizingmatters/) * (@optimizingmatters) * [5 years, 8 months ago](https://wordpress.org/support/topic/error-when-showing-amp-version/#post-13755961) * just fyi: Autoptimize doesn’t act on AMP-pages, so nothing to configure there 🙂 * frank (ao dev) * Plugin Support [Milind More](https://wordpress.org/support/users/milindmore22/) * (@milindmore22) * [5 years, 8 months ago](https://wordpress.org/support/topic/error-when-showing-amp-version/#post-13756193) * Hello [@data1online](https://wordpress.org/support/users/data1online/) and [@martijnatwordpress](https://wordpress.org/support/users/martijnatwordpress/) * I am suggesting that one of the plugins or your theme might behind this as you can check on your non-AMP page, it stripped `https` protocol from several other tags also (check this [screenshot](https://prnt.sc/vxp6ht) ), it’s not AMP plugin specific issue. * to find which plugin/theme might be the cause of this please follow the instruction which I posted earlier. * [@optimizingmatters](https://wordpress.org/support/users/optimizingmatters/) Thank you for your input, the link on `
