Hi
Aida!
First of all, welcome to the Spanish Chrome Forum. If you prefer to speak in English tell me and I'll move this thread to the English Forum. Y si prefieres hablar en español también dímelo y dejamos el hilo en este Foro, que es el Foro en español :-P
We need some more details in order to troubleshoot your problem and help you. First of all, does this happen with one website in particular or with all websites?
Also, it would be awesome if you could send us a screenshot of the error message:
Finally, does this still happen when you open the website in incognito mode?
I look forward to hearing from you ;-)
Cheers,
Adrià
