Hello,
I’ve encountered a compatibility issue between FOX – Currency Switcher Professional for WooCommerce and the Super Page Cache plugin:
https://wordpress.org/plugins/wp-cloudflare-page-cache/

Problem description:
When both plugins are enabled and Disk Cache is turned on in WP Cloudflare Super Page Cache:

  • Changing the currency using FOX works correctly only on the current page
  • After navigating to another page, the currency is incorrect / falls back to the default
  • Prices are no longer consistent with the previously selected currency

If I:

  • disable Disk Cache in WP Cloudflare Super Page Cache, or
  • completely disable the cache plugin

→ FOX works correctly across all pages.

This looks like a caching issue related to currency handling (cookies / session) when disk page cache is enabled.

Questions:

  1. Is FOX officially compatible with Super Page Cache?
  2. Are there any recommended settings (e.g. cookie exclusions, headers, cache rules) to make them work together?
  3. Is there any planned fix or workaround for page cache plugins using disk cache?

I can provide additional details or run further tests if needed.

Thank you for your support.

Hello

If any cache plugin installed on the site enable please in  WOOCS tab Oprions ->"I am using cache plugin on my site" and reset all kinds of the cache. This will redraw prices using AJAX request.

Hello Alex,

Thank you for your reply.

The option “I am using cache plugin on my site” in WOOCS → Options is already enabled, and I have reset all types of cache multiple times.

Unfortunately, the issue still persists.

Hello

Ok, there could be another reason (javascript error, conflict woth another script), please share tmp wp-admin to the site using private area of this ticket, OR also you can create clone of the site on test subdomain by https://wordpress.org/plugins/duplicator/. Also play with currency storages: tab Options ->"Currency storage" -> Save -> Reset all kind of cache
