Hi katev , welcome to the community 🙂
That's odd. Have you tried following their troubleshooting guide to see where the problem could be? https://docs.litespeedtech.com/lscache/lscwp/ts-optimize/#finding-conflicts
If so, then it might be better to contact their support as they know how their plugin works. Unfortunately we're not too familiar with LiteSpeed.
Could you let us know what their response is? Then we'll create a knowledge base article witht he solution for future questions!
