Wordpress LScache Plugin: CCSS not generated
Last Updated on: Wed, 15 Apr 2026 00:00:02 Hi, I use v4.1-rc22. With specific page, I cant have a ccss used by the page. tag does not contain the ccss instructions. Indeed, using debug tool, I found these lines: 06/14/21 18:31:31.616 [my-ip:59620 1 5q6] posting to : https://node5.quic.cloud/ccss 06/14/21 18:31:32.011 [my-ip:59620 1 5q6] [Cloud] response ok --- array ( ccss => / Failed to generate CCSS /, msg => ccss generator error, ) 06/14/21 18:31:32.012 [my-ip:59620 1 5q6] [CSS] con: / Failed to generate CCSS / 06/14/21 18:31:32.012 [my-ip:59620 1 5q6] [CSS] empty ccss [content] / Failed to generate CCSS / It seems a random issue: sometimes, no problem. Here is my report: JGLPBKSV Thanks a lot if you have any idea. Hi, please trigger that error again , and then post the page URL and time ,in UTC format , so I can locate the log about this request. Best regards, Hi Qtwrk, The url which present an issue is, for example (because its not the only): https://lesbijouxdelhermine.fr/categorie-produit/parures/ Here, this is the part of debug log which seems to be related. I get this log after I force cron in order generating the ccss. 06/17/21 10:00:33.325 [my-personnal-ip:56206 1 LbU] [CSS] Generating: --- array ( type => CCSS, url => https://lesbijouxdelhermine.fr/categorie-produit/parures, ccss_type => https://lesbijouxdelhermine.fr/categorie-produit/parures, user_agent => Mozilla/5.0 (X11 Ubuntu Linux x86_64 rv:89.0) Gecko/20100101 Firefox/89.0, is_mobile => 0, is_webp => 1, html => Parures --- Les Bijoux de lHermine / Failed to generate CCSS /, msg => ccss generator error, ) [CSS] con: / Failed to generate CCSS / [CSS] empty ccss [content] / Failed to generate CCSS /` What could I do to understand how to solve this ? Thanks a lot because, after reading with great attention docs.litespeedtech.com/lscache/lscwp, I dont know what to try in addition of this. Best regards Hi, To be more precise, I can add these informations: When I inspect database table my-website_litespeed_url_file , there is no entry for a file of type 3 (ccss) with a url_id matching with https://lesbijouxdelhermine.fr/categorie-produit/parures/ (when I search in table litespeed_url). But when a robot like google inspect this url, in the frontend I see the request for optimizing this url (in page optimization ). Could it be related with group and vary functionality ? In table litespeed_url_file, I can see these item for field vary : guest_mode:1 2fca374e61e4d524e104d6dd133ba2cc and third possibility : an empty field for vary Im going to make new investigations, if some ideas come to me ?. Hello @joy0114 Sorry for the late response due to some miscommunication in the past weeks. I just checked server node for your case and found the URLs you mentioned in the posts which could not be generated have been blocked by our server since the beginning of June. Usually this is due to some past failures. I just cleared the URLs from the blocking list for you so you can try again. From the past logs the more direct error message for your case is typically like this: [2021-06-04T22:59:34.087Z] [vdn] --- [URL] https://lesbijouxdelhermine.fr/toutes-nos-creations [2021-06-04T22:59:34.087Z] [vdn] [ERR] UnCSS: no stylesheets found [2021-06-04T22:59:34.087Z] -------------------------------- [2021-06-04T22:59:34.087Z] [vdn] Response CSS: / null / Looks like our UCSS engine did not find stylesheets for those URLs so it put them into the blocking list to avoid wasting resources on failed ones. If it happens to these URLs again then we need to dig it out further. Best regards, Abe WAHHHOOOOO !Thanks ever so much !You solved the issue for these pages which did not want to be optimized . I do not use UCSS no more, but CCSS are important for me. All ccss are well generated now. Thanks you very very very much. Best regards ]
