Hey there, I'll be able to help you fix your problems with HTTPS. I have over 7 years of experience with Linux systems administration, performing tasks like configuring static Hugo websites (including my own), configuring WordPress websites, cPanel & Softaculous installations, but I also have experience with configuring SSL certificates. I have fixed a lot of SSL problems for previous clients in the past so Is hould be able to help. On top of that, I also have experience with full stack web development and software development, utilising technologies such as PHP with Laravel, JavaScript, TypeScript with Angular, Python, Golang, Docker, and a whole host of others.
As always, if you do have any questions, please let me know :)
