I activated cloudflare within sg optimizer plugin now you can see the problem appeared again.
– select a tour – click book – select date – goes to checkout page- click edit the date – select the new date- checkout page shows previous date or/and product. (No need to submit your booking)
If you have any suggestion, I would appreciate as I want to use sg optimizer and cloudflare together for speed purpose. I will keep as it is as you may check it out
