    Hi,

    After multiple searches and different attempts, I am writing to you in despair.

    For 3 days now, I have been trying to activate the generation of UCSS on my site and it does not work.

    I have the waiting list that is growing and blocking at 501 requests but it is never processed by the cron or by manual triggering.

    There is no file that is created in the ucss folder.

    Do you have a lead?

    Here is my report number: YQMQFRLU

    Thank you

    I tried different configuration with UCSS online enabled or not and the result is the same

    please try this

    go to LiteSpeed Cache -> Toolbox -> Debug setting -> set debug log to ON , log level to advanced , debug include URI, add LSCWP_CTRL=ucss to it , save

    then go to LiteSpeed Cache -> Toolbox -> log view -> clean up any existing log

    now go to back to Page Optm -> CSS -> click that executer UCSS file …. button

    wait for 5 minutes , go back to log view again , copy paste it over https://pastebin.ubuntu.com/ and share the link of log.

    Here is the link with the logs: https://pastebin.ubuntu.com/p/wWr8fbTdWD/

    Not much is happening, the only visible request is the queue deletions

    I have just looked at the web server log files and I can’t find any trace of a quic bot making ucss requests, but I do have a trace for the image optimization service.

    are you sure you clicked the right button ?

    the log shows Query String: page=litespeed-page_optm&LSCWP_CTRL=ucss&LSCWP_NONCE=9fc93f0b82&litespeed_type=clear_q this is the button that clears the queue

    it should be like

    Query String: page=litespeed-page_optm&LSCWP_CTRL=ucss&LSCWP_NONCE=568eca76f2&litespeed_type=gen

    It seems the requested URL is not found:
    [UCSS] cron job [tag] 404 [url] https://rdr-it.com/it/server-smtp-installazione-e-configurazione-con-windows-server/amp [UA] Mozilla/5.0 (compatible; Barkrowler/0.9; +https://babbar.tech/crawler)

    The /amp at the end is creating issues. I would look into why is added.
    There is a filter: litespeed_ucss_url that can change the url. Or maybe AMP plugin has a incorrect setting.
    On the other hand, try deleting the queque and let it regenerate then retry.
