CSS lost on some pages

Hi,

Please check the browser’s dev tool when that happens , you should see some error on CSS request, please check what is the error there, like mix-content , or 404 , or 403 or something ?

Best regards,

Hi,

we do not see this when we review the logs after a user report the problem to us.

now this makes issue more weird.

I mean , if user requested it , even it’s broken link , it will at least, respond 404 error

if you don’t even find any trace of it , that means the user’s browser did NOT even request this file , only possible case I can think of is the mixed content , that case , browser will directly deny it without requesting to server.

pleaase try :

1. check your setting , if both URL are set to https://

and please do double check in database, I have seen a case, even both link in wp setting page shows https:// but DB still gives http:// for whatever reason it was.

2. try implement

Content-Security-Policy: upgrade-insecure-requests;

header , this will instruct browser to automatically send https request when sees http request.

Hi,

Any ideas if this is feasible? If an error occurs with the LiteSpeed CSS merging would the file potentially not be included in the header of the page?

hmmmm ,well , in theory , yes , if something wrong during the CSS optm , it would leads to empty file or not being inserted into page

but I have never seen such case so far, the worst case so far I see if that if page is problematic , LSCWP will bypass itself to do anything.

I was looking at the code

				if ( $this->cfg_css_comb ) {
					$url = $this->_build_hash_url( $src_list );
					// Handle css async load
					if ( $this->cfg_css_async ) {
						$this->html_head .= '<link rel="preload" data-asynced="1" data-optimized="2" as="style" onload="this.onload=null;this.rel=\'stylesheet\'" href="' . $url . '" />'; // todo: How to use " in attr wrapper "
					}
					else {
						$this->html_head .= '<link data-optimized="2" rel="stylesheet" href="' . $url . '" />';// use 2 as combined
					}

					// Move all css to top
					$this->content = str_replace( $html_list, '', $this->content );

					// Add to HTTP2
					$this->append_http2( $url );

did you happen to have CSS push enabled ? if that so , maybe we can check from that direction , like if it is pushed, but not in HTML

Best regards,

Hi,

okay, you do have css push , but still , we will need to a way to reproduce the issue to verify your theory
