Technical problems on the website

[Teresa Maria]

Unfortunately, every time I try to log in, the browser informs me that the website of Forum 12 o'Clock High is insecure and my data may be stolen by third parties. Under Google Chrome, I only get the word 'insecure' (in Polish, because of the settings of my browser and my computer in general), but Mozilla Firefox actually tries to prevent me from logging in.
Could you, please, update your security certificates or do whatever is necessary to make this site secure?
Thank you very much in advance.

I have also just found this as well. I work in computer security and if you do not secure your website you are setting yourselves up for a lot of problems.
