wordpress cache problem

I disabled and enabled all plugins and theme

Did you deactivate them all and then check the Twenty Seventeen theme to see if the issue persisted?

Maybe you should contact WP Rocket for support?

i deactivate a plugin and problem fixed.
but first byte time is still very slow and i am using very light weight theme . I contacted my hosting provider and they told me that this problem is occurring from your side.

From whose side? We aren’t involved in your website in any way. Can you explain detail what the hosting providers said?

Your side means from My wordpress dashboard

If you’re facing a performance issue with your WordPress environment, can you show us your website with all plugins deactivated and the Twenty Seventeen theme active? Then we should be able to replicate the issue. At the moment your guess is as good as ours as to why it’s slow.

It would also be useful to know the actual time it takes for the first byte, instead of “very slow”.

i activated twenty thirteen and disable all plugins

its taking 1.5 sec to 2 second

its taking 1.5 sec to 2 second

DNS resolution for your domain name tipsntrick.in alone is taking 300 milliseconds (check here: https://www.ultratools.com/tools/dnsHostingSpeed)

Compare that with just 3 milliseconds for www.ads-software.com.

So it shouldn’t be surprising that your TTFB will be 1.5 seconds.
