Member seeing a white background with ad

Hello I am the webmaster of a forum and one of my members is having trouble every time he opens up a thread on our site. He receives this error: https://media.discordapp.net/attachments/487847342901559317/522336597354610689/Nygshot.jpg?width=973&height=588


Its basically a white background with a single ad. Unfortunately he is the only one experiencing this error. It pops up in both IE and Chrome and he has cleared his cookies in both. Any idea on what can be done to help fix it?

Hello,

We made a major change to the advertising codes imposed by our service provider CRITEO and since then, this bug has appeared randomly. This does not come directly from their advertising codes but more than conflict with their integration.

The technical team is working on solving the problem but the randomness makes it quite complicated to understand. In addition, a simple reloading of the page allows you to have the page displayed correctly, which is even more disturbing.

I will be in touch to keep you informed.

We apologize for the inconvenience.
