Wordpress LScache Plugin: 404 error with guest.vary.php
Last Updated on: Wed, 15 Apr 2026 00:00:02 Hi, Does somebody known why I see a 404 error on file /litespeed-cache/guest.vary.php when I test my website on Gtmetrix ? I enabled guest mode, but disabled guest optimization because this website is hosted on server which does not support mobile separated cache (LITESPEED_SERVER_TYPE = LITESPEED_SERVER_ADC). Does this kind of server support guest mode ? Thanks a lot. Best regards Hi, What do you mean by 404 error on file /litespeed-cache/guest.vary.php ? Maybe you can take a screenshot or send the GTmetrix report page? Guest Mode could be turned on for all the supported litespeed server types. Although the specific optimization features available for each server type or settings may be different, the available features will be used. Regards, Abe Hi, Thanks for your answer. Here, the GTmetrix report: Gtmetrix report Sorry, I did not express the issue correctly: this is the post request which seems to be problematic: image-1 Here the header of request: image-2 And the response: a,body,div,form,h1,html,label,li,span,ul border:0 font-size:100% font-style:inherit font-weight:inherit margin:0 outline:0 padding:0 vertical-align:baseline html -webkit-text-size-adjust:100% -ms-text-size-adjust:100% body margin:0 footer,header,nav,section display:block a background-color:transparent a,a:visited text-decoration:none img border:0 button,input color:inherit font:inherit margin:0 button overflow:visible button text-transform:none button,input[type=submit] -webkit-appearance:button button::-moz-focus-inner,input::-moz-focus-inner border:0 padding:0 input line-height:normal input[type=search] -webkit-appearance:textfield box-sizing:content-box input[type=search]::-webkit-search-cancel-button,input[type=search]::-webkit-search-decoration -webkit-appearance:none .ast-container max-width:100% .ast-container margin-left:auto margin-right:auto padding-left:20px padding-right:20px h1 clear:both h1 color:#... [truncated to save space (86532 more bytes)] Thanks for your explanation about guest mode. For me, I disabled optimizations for this mode. Best regards Your LSWCP_PLUGIN_URL constant seems to be wrong somehow. Did you change your WP content folder path? Hi, Path for plugins had been changed, but /wp-content exists and contains /ajouts (for plugins), and /litespeed (which contains ccss, css,js, crawler?). And /wp-content/ajouts/litespeed-cache/guest.vary.php also exists. Is there here something abnormal ? Thanks Hi, if you have changed the wp-content dir please try add this at top of your wp-config.php define( LSCWP_DIR, /absolute/path/to/your-real/wp-content/plugins/litespeed-cache/ ) Best regards, Hi qtwrk, Yes ! Thank you very much: you solved my issue. The error disappeared. Have a good day. Best regards
