Title: CSS doesn’t generate Last modified: June 3, 2020 --- # CSS doesn’t generate * Resolved [cosmins](https://wordpress.org/support/users/cosmins/) * (@cosmins) * [6 years ago](https://wordpress.org/support/topic/css-doesnt-generate/) * Hi guys, All of a sudden, CSS doesn’t seem to be generated anymore inside the tag, cleared all cache & transients. We do have also a staging environment with the same setup – same plugins (& versions), same theme and there everything is working properly. * What could be the cause? What should I be looking into? Please help. * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fcss-doesnt-generate%2F%3Foutput_format%3Dmd&locale=en_US) to see the link]_ Viewing 11 replies - 1 through 11 (of 11 total) * Plugin Author [Weston Ruter](https://wordpress.org/support/users/westonruter/) * (@westonruter) * [6 years ago](https://wordpress.org/support/topic/css-doesnt-generate/#post-12932752) * Are there any validation errors showing up when you click “Validate” under the AMP admin bar item? It may be due to having excessive CSS? * [selu](https://wordpress.org/support/users/marius2012/) * (@marius2012) * [6 years ago](https://wordpress.org/support/topic/css-doesnt-generate/#post-12934153) * Hey [@westonruter](https://wordpress.org/support/users/westonruter/), * I’m following up on the same site which my colleague reported. It’s some kind of inconsistency: * Viewing the AMP page, [https://www.codeinwp.com/blog/?amp](https://www.codeinwp.com/blog/?amp), I see the CSS usage at 1% -> [https://share.getcloudapp.com/L1upGm57](https://share.getcloudapp.com/L1upGm57) but when reviewing the validation details for that page, I see `Total CSS size after minification: 41,922 B` -> [https://share.getcloudapp.com/8Lu7G8wN](https://share.getcloudapp.com/8Lu7G8wN) * Any idea what could be causing this discrepancy? * We are not using Object Cache, the generated CSS is stored in transients. * Plugin Author [Weston Ruter](https://wordpress.org/support/users/westonruter/) * (@westonruter) * [6 years ago](https://wordpress.org/support/topic/css-doesnt-generate/#post-12934389) * Please share your Site Health info. Perhaps there is a plugin conflict? * [selu](https://wordpress.org/support/users/marius2012/) * (@marius2012) * [6 years ago](https://wordpress.org/support/topic/css-doesnt-generate/#post-12934482) * Hi, * I’ve attached the health info * [https://gist.github.com/selul/7659e846243552f4b4f58089f878d860](https://gist.github.com/selul/7659e846243552f4b4f58089f878d860) * We haven’t been able to isolate any conflict! Except for transients, is there any other place that could store the CSS generated? * Plugin Author [Weston Ruter](https://wordpress.org/support/users/westonruter/) * (@westonruter) * [6 years ago](https://wordpress.org/support/topic/css-doesnt-generate/#post-12934509) * That’s strange. Are there any validation errors being reported for the CSS? You shared a screenshot of the stylesheet summary, but what about the table above? * Plugin Author [Weston Ruter](https://wordpress.org/support/users/westonruter/) * (@westonruter) * [6 years ago](https://wordpress.org/support/topic/css-doesnt-generate/#post-12934557) * I bet you have a CSS rule that contains `i-amphtml-` somewhere. * Plugin Author [Weston Ruter](https://wordpress.org/support/users/westonruter/) * (@westonruter) * [6 years ago](https://wordpress.org/support/topic/css-doesnt-generate/#post-12934919) * Actually, if that were the case then I’d expect the `style[amp-custom]` element to be removed entirely. See [https://github.com/ampproject/amp-wp/issues/771](https://github.com/ampproject/amp-wp/issues/771) * For some reason it seems the stylesheets loaded via in `link` elements are getting dropped, but I don’t know why would be. * Examining any validation errors that are being reported above the stylesheets metabox is the next place to look. * [selu](https://wordpress.org/support/users/marius2012/) * (@marius2012) * [6 years ago](https://wordpress.org/support/topic/css-doesnt-generate/#post-12936279) * Hi [@westonruter](https://wordpress.org/support/users/westonruter/), * All the validation errors reported by AMP on that page are JS related which has the markup status `Removed`, nothing related to the CSS. * Any idea what could prevent the fetching of the external CSS files? * [selu](https://wordpress.org/support/users/marius2012/) * (@marius2012) * [6 years ago](https://wordpress.org/support/topic/css-doesnt-generate/#post-12936516) * Hi [@westonruter](https://wordpress.org/support/users/westonruter/), * I’m following up on this issue, it seems it was a CDN compatibility issue. * Right now everything is ok. * Plugin Author [Weston Ruter](https://wordpress.org/support/users/westonruter/) * (@westonruter) * [6 years ago](https://wordpress.org/support/topic/css-doesnt-generate/#post-12939027) * Please share the details about what the CDN compatibility issue was so that others in the future can benefit. * [selu](https://wordpress.org/support/users/marius2012/) * (@marius2012) * [6 years ago](https://wordpress.org/support/topic/css-doesnt-generate/#post-12940436) * Hi [@westonruter](https://wordpress.org/support/users/westonruter/), * I wish I could but I’m not sure what was causing this and the hosting company that we use doesn’t offer too many details around this. Basically this is their answer: * ``` We are aware that there are at times issues with our CDN, and have included a note about when you go to activate it: Kinsta CDN may not be 100% compatible with multisites and custom setups. There are often cases (due to a customized setup) where it is necessary to disable/re-enable the CDN cache to fix certain layout issues ``` * Based on your feedback regarding a possible issue with fetching of the external CSS styles, I have reported that would be an issue with the CDN and they have recreated the CDN distribution which magically fixed the problem. * I hope this helps!
