It worked but after lots of troubleshooting. First plugins just doesnt want to get deactivated and when I deleted from plugins folder. The website went in loop. Not loading.
After renaming plugins folder site came back. Again installed, activate and then deactivate. Installed again then I just did one change which is “Strip response cookies on pages that should be cached” changed the mode to “on” because again caching was not working. But at last it worked. Thanks a lot for guidance.
