Hi all,

I am running OC 3.0.2.0, few weeks ago I installed a caching extention for faster loads of the pages, it works great, until today I decided to show my friend on his iphone how fast is my website. I was not able to scroll most of the pages, yes all these pages were cahced for faster load already. The issue is only with Iphone phones, all anroid phones are ok. Once I found out the issue I tested on 3 other Iphone and they were not able to scroll. Here comes the interesting part.

I cleaned the page cache and all iphones started scrolling. Once it was cached by iphone it worked with android phone also. But when a page is cached for the first time by android phone, you are not able to scroll that page on iphone :crazy:

https://ledsvetlini.com/Kak-da-izberete ... ki-za-kola - For this page I disabled caching you can check you can scroll
https://ledsvetlini.com/Signalni-krushki - this page is cahced for first time with android, if you have Iphone you should not be able to scroll it.

most probably there will be more pages that will get cached by online user and you won't be able to scroll from your iphone

How this can be fixed?

:laugh: :laugh: :laugh: :laugh: :laugh:

I have a complementary question as I am OP, If I removed the cache extension, how could I make the store super fast again?
Please don't say 'Adding the extension again.' :laugh: :laugh:

Maybe so but the issue here is that your caching extension page caches stuff it should not, client-side code which is obviously specific for android or iOS.
When you page cache this stuff indiscriminately, you are asking for trouble looking for an easy-lazy performance fix which do not exist.

You could of course also just fix iOS if that seems easier to you.

It caches pages that are ok to cach like home page, cattegoriesproduct pages and etc, caching is not active for cart, account, favorite and etc, also I disabled some for pages. How I can edit CSS?

Well, apparently your "ok to page cache" pages are not "ok to page cache", probably because they are filled with journal generated inline css and javascript which are obviously more device OS specific than desired.

Add a better caching extension such as Nitropack Cache from iSense.
