Does browser cache gets disable in cloudflare when plugin is enabled? It seems that setting got changed to respect existing headers. Should I re enable it?
– No it should always remain Respect Header. Do not change it.
Do I need to edit nginx.conf file for the plugin?
– Yes, if you have any other nginx rule added for adding cache-control or expire header to the static files, please remove them and then inside this plugin settings under Cache tab, enable the add browser cache rule option. Then click on the link to copy the nginx rule created by the plugin and put them in your nginx.conf file.

Don’t forget to restart your nginx and PHP after doing this.
This will add the proper cache-control header for your static file and telling Cloudflare to cache them properly.
Also I noticed that blocking time gets high when I enable bot fighting mode. I know its not related to the plugin but if you have any ideas I would appreciate it.
– It’s because when you enable bot fighting mode, Cloudflare adds a bit if JavaScript to the page which increases the blocking time. Unfortunately there is no other way for this. So, I would suggest not to inject that JS.
Thank you Saumya for your quick response and very good explanation. Ive added needed code to my nginx.conf but it seems that browser cache still does not work.

can you share your site URL so that I can check on my end?
If you have added the nginx rule check the static files if they have the cache-control header as specified in the nginx config file.
yes here it is.

I really appreciate your help, thank you.

I really don’t think your nginx rules are taking effect as I do not see any cache-control header for your static files. Screenshot: https://i.imgur.com/xRJ7bJY.jpeg
Have you restarted your nginx and PHP and purged the whole cache from Cloudflare?
Restarting server did not help, but I believe it started to work after cache purge. Could you please confirm that it works as it should?

Yup. All good now. The Cache Control header is now properly getting added and you got static file cache both at browser and CDN level.
If you like the plugin, please do consider sharing a review in the review section of the plugin.
Just did. Thank you for your help! Also do you recommend any other performance plugins that could improve performance even further?
@allnamestaken look in third party tab of SPCFC plugin
I just realized that my sitemap.xml stopped working and started displaying 404.
I had to remove this line from nginx config to make it work
location ~* \.(xml|xsl)$ { add_header Cache-Control “no-cache, no-store, must-revalidate, max-age=0”; expires -1; } any advice?
using seo framework to generate sitemap

Hi @allnamestaken,
Which SEO plugin do you use to generate the sitemap? That rule that you deleted does noting but adding a proper cache control header to your sitemaps so that they doesn’t get cached in Cloudflare CDN and always gets served from the origin server.
Also do you recommend any other performance plugins that could improve performance even further?
– You can definitely use Perfmatters (a great plugin) and also Autoptimize if you want.
Sorry for the delayed reply. For some reason I did not received any email for your reply.
Im using seo framework to generate sitemap
Adding location ~* \.(xml|xsl)$ { add_header Cache-Control “no-cache, no-store, must-revalidate, max-age=0”; expires -1; } throws 404
Also I dont think its related to this plugin but I have an unusual issue. If I go to my page source my meta title tags are correct, but for some reason google is using my on page titles instead of title tags set by seo framework. Updated pages have been cashed by google yet search results show different tags. I hope it makes sense…

I honestly don’t know how that rule can through a 404. That rule is simply saying if there is a XML or xsl file in the server add that cache control header for that file when sending to users.
Regarding Google thing. Meta Title don’t guarantee Google will use that Title. If their system think, some other part of your content works better as Title or Meta Description – they will use that.
Saumya so this rule does not work “location ~* \.(xml|xsl)$ { add_header Cache-Control “no-cache, no-store, must-revalidate, max-age=0”; expires -1; }” because its meant for static files and sitemap.xml does not exist as its being dynamically generated by the seo framework and I assume other plugins as well.
I do not know if the sitemap will be cashed without the rule, but probably not since google search does not find mydomain.com/sitemap.xml
Just sharing what I found as Im sure more people will have this issue in the future.
