because I am not sure, how much time it takes to you and your team, I am going to deactivate the Litespeed plugin now (I need to make some tests with other things).
You can I activate it again whenever you need, it's absolutely no problem.
during today I made some more tests and I found out that it doesn't work completely right.
I'll describe you what I found out. The difference is between two scenarios.
1. I clear the cache and then use VPN to simulate SVK location. I visit the website and there is no cache, so the first visit is with no cache and after that it creates the cache for visited pages - that's correctly - all pages are correctly with EUR currency - everything's fine.
Then I close the browser, open the new one without VPN (so CZ location is applied). I visit the website, there is no cache for CZ location, so the first visit is with no cache and after that the cache is generated. All pages with CZK currency - everything's perfect.
2. The problem is here
When I'll do the same as above, but I start with CZ location, it doesn't work. I'll describe it again for sure.
I clear the cache and open the anonymous window without VPN (CZ location is applied). I visit the website and there is no cache, so the first visit is with no cache and after that it creates the cache for visited pages. All pages are correctly with CZK currency - everything's fine.
Then I close the browser, open the new one with VPN - SK location. And the first visit is from the cache with CZK currency. So it doesn't work as it should.
I am not sure, where exactly is the problem and why the cookies aren't used when CZK cache is generated.
When I visit the page from SK (EUR variant), there are set 4 cookies, the last one is important:
wcml_client_currency
wcml_client_currency_language
wcml_client_country
_lscache_vary=wcml_currency%3AEUR
But from CZ (CZK variant), there are set only 3 cookies:
wcml_client_currency
wcml_client_currency_language
wcml_client_country
If I understand it well, the cookie _lscache_vary is important, because it's the cookie to mark different caches. That's why CZK currency can be shown after EUR (because there is this vary cookie), but when the CZK cache is created (without this vary cookie), it's considered as the main cache and it's served for all visitors.
I am not sure how to proceed now. How to make WPML + LS Cache work. Please, can you help me?
At the moment I want to verify, is the code I provided still active in functions.php?
You mentioned that at first it worked OK, did it work and then stop working? This will help us further investigate as i dont have access to the backend to further review.
It worked, or it was caused because maybe I've started from SK location (scenario 1) - I am not sure. When I tested it, I checked that 3 cookies are set for both currencies, but I didn't know, that there should be also ls vary cookie, so I didn't check it.
Only when I've noticed that it doesn't work, I've started to looking for why and I've found out what I've written before.
I tested to add some code to the functions.php and enable Cache REST API. After that it started to work. But I was debugging another problem, so I disabled Cache REST API and removed the code = original status (only with code from you). And it still works...
I will test it during the weekend and I'll let you know if there will be any problem, or if it works.
I don't understand what happened, but for now it works and you don't have to check it.
