Page Cache not working as expected

Hello,
This should already be taken care of in Performance>Page cache, Purge Policy: Page cache sub-box.
Try enabling:
Post comments pages
Post author pages
Post terms pages
Save all settings and purge caches.

Hi Mark,
Even after enabling the options which you suggested, I still see home page is not getting reflected with new posts.
Another issue when I enable Page Cachr, it is showing almost 12 hours old posts on the home page. My website is a news website so we post news once in every 5 mins.

Hello,
Are the posts showing if you purge the cache?

Hi Mark,
Yes I have purged the cache.
We got another issue today and due to this we are thinking of deactivating W3 Total.
We had huge traffic on website, 4000 users were preset at a time and site was not loading from cache. Due to which CPU spiked and site crashed.

Regards
Praneet

Hello,
Can you please share what settings you have enabled?

Hi,

Thx for quick response.

You need all sections?

Best regards,

Hello,
I see that your website is back up. Do you have DB cache and Object cache enabled? And if so what is the caching method that you are using?

Can I have your email ID, so that I can send the screenshot.

Page Cache = Disabled
Minify = Enabled
Opcode Cache = Enabled
Database Cache = Disabled
Object Cache = Enabled
Browser Cache = Disabled

When I enabled Page Cache, I have enabled these
Cache Posts Page = Yes
Don’t Cache Front Page = Yes
Cache SSL = Yes
Cache Preload = No
Purge Policy = Yes for (front page, Posts page, Post Comments Page, Post author page, Post terms page, Blog Feed) rest all are unchecked.

Hello,
Are you using any other caching solution?
And again. When you empty all caches do those new posts appear?
