Blank screen in Kommo

Here, we will give some instructions on what to do if you get a blank (gray) window without buttons when opening Wazzup chats in Kommo:

First method: click on the “Save” button

1. Go to the “Settings” section→ Integrations → “Installed” tab → click on the Wazzup app.

2. A window will open with instructions on how to install the app. Click under the instructions to “Save”. The button may look disabled, but click it anyway — it works.

After that, try to open the Wazzup chat window.

Second method: disable cookie blocking

First of all, try logging into your Wazzup account using the same machine and browser via the following link: https://app.wazzup24.com. If everything is fine, it means that the error is caused by your browser which is blocking cookies for embedded windows.
