If the error continues even after following this tutorial, we ask you for the following information to identify the problem.

As part of our ongoing improvements, our technical team strives to ensure error-free performance. However, due to the diversity of computer configurations and variability between countries, we cannot always replicate all situations. For this reason, we request your collaboration in identifying any issues you may encounter.

To provide you with a solution as quickly as possible, we ask that you send us a screenshot in developer mode. While it may sound complicated, we will guide you through some simple steps using the following illustrative image.

We show you a video that explains the procedure of the clicks you must make. In our case, we don't see any connection error, so we only see our number with the green check mark. If you see yours in yellow or red, you must click on that option and then refresh the page following the video.

Here are the steps to follow:

Step 1: Click on the three dots located in the top right corner of Google Chrome. Scroll down almost to the bottom and you will find the option "More tools" and then "Developer mode".

Step 2: A window similar to the one shown in the "Steps to take a screenshot" image will open. Click on the "Console" tab, marked with the number 2.
Step 3: Keep the console open and click on the refresh screen button, identified with the number 3.
Step 4: Try to connect to WhatsApp Web by opening the "Whatsender" extension. Remember to keep the console open and click on "Open WhatsApp Web", as shown in the image with number 4.

Step 5: As a final step, take a screenshot showing all the information displayed in the console. It's important for us to verify that you are indeed on WhatsApp Web. It's not necessary to display your conversation history. We provide you with a reference of the content that should be included in the screenshot: on the right side, the log of the errors, and on the left side, the evidence that you are on WhatsApp web.

Step 6: Send us this image to support@what-sender.com or through our support form. At this moment, our entire support team is here to assist you in resolving any issues with this new version.
