Sometimes, the installation may get delayed for a while, or you may not see the confirmation after clicking the 'Check Now' button. In that case, check if you're using a cache plugin on your WordPress (such as W3 Total Cache) and purge the cache before you check again.
Always make sure to check your website in an incognito window (private window) without any extensions to see if you are able to see the Gist chat messenger on your website. If you do not see the messenger button on your website but the installation process is completed successfully, then go to your the Messenger Configure Settings in your Gist account (Settings > Messenger > Configure) and check if the messenger is enabled or not.
How to check if the installation process is completed successfully?
If you followed the steps mentioned above, but still do not see the Gist messenger on your site, it could be that the installation is not complete.
You can check whether or not Gist has installed successfully on your website, by checking your browser console for errors related to Gist. Here's a simple check that you need to do.
Open your website in a new incognito window, right-click anywhere on the page, and choose 'Inspect Element' (or Inspect), and you'll see your browser's developer tools pop up.
Click on 'Console', type Gist , and hit enter.
Case 1 - Successful Installation
If Gist is successfully installed, you will see the following.
Case 2 - Successful Installation
If Gist is not installed successfully, you will see an error in the console.
If you see this error, then the installation is not successful.
In this case, if you're using the Gist WordPress plugin, then remove the plugin from your WordPress and try installing once again by following the steps laid out here .
In both the cases, check if you have entered your project ID correctly and that you have purged the cache.
Also check if your website domain is the same as the domain associated with your Gist project (which you entered in the project settings page), or at least that your domain is whitelisted for your project.
