Good evening, For some time, it is impossible for me to access some websites, from a macOS or from a linux. The reasons seem diverse but I am sure there is a common problem. Each time the website appears for a fraction of a second, then an error message appears. For example, on the website sadeya.com, the message is "thank you to come back a little later, sadeya is in maintenance ...", or even the site widrax.com which shows me "PHP Fatal error: Call to Undefined method mysqli_result :: fetchAll () ". What brings me to believe that the problems have a common origin is that it happens to me only on streaming sites. Will not this be a problem from the firewall or DNS? And I don't know why, it works on some other macbooks... Thank you for your help !
