I have a sitecore commerce site in my local machine and when I click the 'Book Now' button on the website, it shows this error message:

GetCurrentCart: Activation error occured while trying to get instance of type ICacheManager, key "Sitecore_CommerceCartCache"

enter image description here

The commerceengine site which is in the same machine is also up. I tried restarting IIS but no luck.

These are the registered logs:

probably it is too late to answer this, but as a reference for other which encountered the same problem. After installation i have got the same error, the reason for me was, i forgot to merge the merge configs to the web.config as mentioned here:

  1. Go to the Website folder and open the web.config file.
  2. Navigate to the \Website\MergeFiles folder.
    • Merge the contents of the Merge.CommerceServer.config file into the web.config file.
    • Merge the contents of Merge.Commerce.Storefront.config file into the web.config file.
  3. Save your changes to the web.config file.

Hope it helps others.
