Thank you for reaching out, and I apologize for the inconvenience you are experiencing with your website.
I would like to clarify that I have not logged into your site, as the access details were provided over the weekend, outside of my working hours.
Since this appears to be a server-side issue (500 Internal Server Error), I kindly recommend contacting your hosting provider directly. They will be able to review the server error logs and assist you in resolving the issue promptly.
Thank you for your understanding.
Best regards
