I have created a question using user A. I always run into timeouts after 10-15 seconds, when I try to visualize it.
"We didn't get an answer back from your database in time, so we had to stop. You can try again in a minute, or if the problem persists, you can email an admin to let them know."
A different user B (who happens to be an admin user) can run the visualization just fine, even though it sometimes takes two minutes to finish.
@exo Can you share the names/URLs of the extensions? I'm curious what they are doing to cause such a strange problem. Almost sounds like some antivirus extension.
