* I am unable to upload a csv file of products to my site from the frontend vendor
dashboard site. This is critical because vendors will need to upload products
to sell on my site.
* The error is below:
403 Forbidden
* 403 Forbidden
* A potentially unsafe operation has been detected in your request to this site.

* Put your Wordfence firewall into “Learning Mode”, then perform your typical CSV
file upload so that Wordfence can learn what constitutes a valid interaction
for your site.
* Once the interaction has been whitelisted by the firewall, turn off “Learning
Mode” and enable the Firewall again.

* Hello,
* As @blubearmedia pointed out you can go to the **“Firewall”** page and switch
the firewall to Learning mode. If you need more information on how to use **“
Learning Mode”** then please take a look at our documentation below:
* [How to use Learning Mode](https://docs.wordfence.com/en/Web_Application_Firewall_-_How_to_use_Learning_Mode)
* Finally, it is very important that once the firewall whitelists the CSV file
upload action then you need to go back to the **“Firewall”** page and switch
the firewall back to **“Enabled & Protecting”**.

* Hello,
* Can we check to see if it is Wordfence causing this new connection error please.
1. Try to upload a CSV file again to make sure that the error still exists – **“
Something went wrong we cannot make connection to the server”**.
2. Next, go to your plugins page and de-activate Wordfence.
Try and upload your
CSV file again.
3. If the CSV file upload is successful then go back to the plugins page and activate
Wordfence. Now try to upload a CSV file again to double check that you get the
connection error again.
* Thank you.
