On October 19, 2021, we have enabled single-sign-on for our Plesk Support Center to provide a seamless login/account experience. This implies that you’ll be able to use a single account across any of our web-facing properties.
If you had already registered your account at Plesk 360 (formerly known as My Plesk) please use one for login. Otherwise please re-register it using the same email address as your existing Zendesk login (support account). It’s essential that you use the same email address on our support center to ensure that your tickets stay attached to the same account.

    When I check my site in this tool:


    LSCache is not supported.

    I really install Litespeed and Litespeed cache plugin and config correctly. But I got the above message.

    How to fix it. Thank you so much.

    Hi Christopher Danks,

    The bug is being addressed and will be fixed in future Plesk updates, however, there is no ETA at the moment. The warning can be safely ignored as it will not cause any issues. As a possible temporary solution in your case, you can probably filter out specific words from log files using grep or such, e.g., as described here or here. Hopefully, this helps.

    I just came across this error today.  Can this bug be fixed OR have plesk not report the issue?


    We are moving 1100 accounts from cPanel to Plesk and in our tests we got errors on all the accounts and its hard to see real errors when all 1100 report this issue.
