How to check your version

  1. Log in to WordPress and open Plugins > Installed Plugins.
  2. Find Click to Chat. The version number is under its name. If it is lower than 4.45, your store is affected.
  3. No login to hand? Open https://yourstore.com/wp-content/plugins/click-to-chat-for-whatsapp/readme.txt in a browser, with your own address in place of yourstore.com, and read the Stable tag line. Some hosts block this file; then use step 1.

How to fix it

  1. Make a backup, or better, a staging copy of the store (most hosts have a one-click staging button).
  2. On the copy, update Click to Chat to 4.45 or newer: Dashboard > Updates, or Update now on the Plugins page.
  3. If no update shows, it may be a paid version whose licence has run out: download the new version from the seller's site and upload it.
  4. Place a test order on the copy: add to cart, check out, pay with a test method. Check the pages that use Click to Chat.
  5. If everything works, make the same update on the live store and place one more test order.
  6. If you no longer use Click to Chat, delete it instead of leaving it deactivated.

Questions

Which Click to Chat version fixes it?
Version 4.45 or newer fixes all 2 issues on this page.
How do I know if my store is affected?
Your store is affected if it runs Click to Chat older than 4.45. In WordPress, open Plugins and read the version under Click to Chat. Without logging in, open yourstore.com/wp-content/plugins/click-to-chat-for-whatsapp/readme.txt and read the Stable tag line.
I don't use Click to Chat any more. Is a deactivated copy safe?
Deactivating it lowers the risk but leaves the old code on your server. If you don't use it, delete it; if you do, update it.
Can someone fix it for me?
Yes. We update the store on a copy first, place a test order, and only then make the same change on the live store, for a fixed price.
