Disabling conflict plugins

Let’s try this:
Disable Object Cache ( from here: https://docs.litespeedtech.com/lscache/lscwp/cache/#object-cache ) clear cache and try now the admin pages.
Then you can enable Object Cache again.

If this is not working, please create a report and share me the number generated. This can be done from: LSC => Toolbox => click on “Send to Litespeed” and share that number.

Thank you, Tim
