Hello,
Is this compatible with 4.4.4?
Thank you!

Thank you. I installed and I didn't saw the icon (in mobile or desktop) even adjusting the css settings mentioned here in this thread.
I'm using a custom theme, do I need to adjust something else or it should work as is?
Thank you again!

Your cache level should definitively be Standard, the default setting. Using anything else will break IPS' cache busting feature, which is needed to recache static assets.
Cache TTL can come down to a matter of preference. Considering important resources like CSS and Javascript assets are cache busted as needed, it's safe to use values up to even 30 days if you so wish.
The potential concern with this is, if image attachments are deleted but left embedded into posts as an example, they will still display as cached in the users browser for however long you set this to. So, it can be a minor privacy concern, as IPS currently does not automatically remove image embeds from posts when attachments are deleted from the users control panel.
That's really the only thing to keep in mind. Otherwise, I recommend at least 7-days personally.
 
Outside of these, there are several useful features Cloudflare provides that I recommend taking advantage of.
Note, some of these features are Pro only, but if you're a Free user, use the ones that aren't. They help if even a little bit and there's no reason not to.
Now, if you have a high traffic website and you can afford it, I personally believe it's worth upgrading to the Pro plan.
 
But to get started with the optimizations, under the Speed tab, go to Optimization and make sure these settings are enabled.

Polish with WebP enabled can be hugely useful if you have a lot of PNG attachments / avatar uploads on your site, as WebP can provide substantially better lossless image compression compared to PNG.
Auto Minify is disabled by default and you should enable it. The actual performance improvement is small, but it's still an improvement with no risks, so there's no reason not to use it.
Brotli, again, small improvements, but no risks and and no reason not to use it for clients that support it. All the overhead involved in performing the compression is handled by Cloudflare here after all.

Enhanced HTTP/2 Prioritization and TCP Turbo are again zero risk performance improvements and if you have access to them you should enable them.
Mirage can be great in theory for mobile browsers by automatically optimizing images on slow networks. It's in beta, but I do definitely recommend enabling this. Roughly half the of the internets traffic today is mobile. These optimizations can yield huge benefits to your users.
Rocket Loader I do not recommend enabling, as it can cause functional and perceptional issues with IPB. It makes things look and act in strange ways, and can potentially just break things. Rocket Loader is one of those things that works well for some sites, but is awful for others. It's not great for IPB in my experience. I say the same for PageSpeed JS optimizations and so on as well.
Under the Network tab, make sure these settings are enabled.

All of these are, again, zero risk performance optimizations. No reason not to use them.
Argo tunnel can potentially be useful as well, but note that it can be extremely expensive depending on your bandwidth requirements. It's an additional $0.10/GB of bandwidth. Do not enable it until you have at least a months worth of bandwidth analytics logged from Cloudflare so you have an idea of how much you can expect to pay if you enable this feature.

Hello,
I honestly believe that this needs to be covered and start thinking in someway to be able to share posts more social networks friendly.

Hello,
I honestly believe that this needs to be covered and start thinking in someway to be able to share posts more social networks friendly.

I apologize for continuing to be annoying, but I've been using this topic to report the difficulties I have in managing the community without this essential tool.
Our forum is a community of independent travelers, backpackers, hikers and thru-hikers.  Among our members is this couple from the post below, both have been in the community for over 10 years. They have traveled almost every trail in Brazil and not just the short trails, they have traveled the main long distance trails of the country, some of them more than once.
To publicize their topics and other participants we use our social networks that are very well shared and bring half of our traffic today. See in the image below what was the photo that the system chose for us to divulge the inspiring adventures of an elderly couple practicing long distance trails.

How can you post this post with this featured photo on social networks?
They have just arrived on the road and are doing this post, you and we are tied hands without being able to program it on our Facebook page. If someone shares this in your profile, this will be the photo that will be released.
What did I do before to solve this problem?
I entered the IPB TAGS editing system and manually placed the og: image tag.
What happened and why do not I do it?
Because I realized a lot of time later using this method, that the tag system created a bug causing multiple pages to repeat the meta tags.
I was advised by you not to use the tag system for this purpose anymore. To delete all the tags you had included, leaving only one tag on the main page.
From there to here I did not post the content of the Forum on our Facebook page, just the content of our blog.
This is a real account of a real problem that makes day-to-day management of content disclosure in social networks impractical. If there is no intention to include a resolution to this problem in the next versions, could not then create a plugin so that the page administrator could customize the featured image, just including it in the meta tags?
