Wordpress LScache Plugin: Cache miss despite every site crawled?
Hey there, I have a crawler running and it shows every dot in green. But when I open my website I always get a cache miss on first load. Only after I visited a page manually I get served the cached version. As I understand it shouldnt be that way. How can I fix this? PS: After I purge all caches the crawler still shows everything in green and sits idle. Shouldnt the crawler show everything in grey and restart immediately? Or do I need to start crawling manually? Hi, no , crawler wont re-start immediately , and the status (the color dots) are not real-time , it is the status on last crawler run it did the crawler will only start again after it reaches next crawler interval time Best regards, Thanks for clarifying! However, the problem remains: ? I purge the page ? I start the crawler ? after that every dot is green or blue ? if I open a page it shows page miss (however, after THAT the page loads from cache, even on a different device) Any idea why this happens? Hi, pleas enable the debug log to ALL IP , then run crawler , after it finishes , check file /wp-content/debug.purge.log see if there is any purge happened Best regards, Thanks, I checked. There are multiple instances of a cache purge.

I cant make anything out of this. Any suggestion what I should do? Is it purging just because of this CSS bug? Hi, 98d_UCSS.b3ac664ababa96387f2c5d84e16666cc it has UCSS tag, , the ucss generation is async , which means it is generating in background , so this is what happens when you access a page , it doesnt have ucss, page gets cached , and ucss put in queue in background , once the ucss is generated, it will purge this page in order to insert the ucss into it you can either disable ucss , or wait for all ucss generation complete , then it wont purge page like this anymore Best regards, Hey qtwrk, thanks for your reply! I fixed the CSS bugs and tried it again: made no difference. Then I disabled all CSS optimizations and tried it again. But still: same problem. Immediately after crawling the whole site theres no cache ready. Only if I visit a page manually a cache is generated thats valid even on other devices. In the log is no purge after the crawling documented now. Any idea whats causing this and what else I could check? please create a ticket by mail to support at litespeedtech.com with reference link to this topic we will investigate further
