Thanks for reaching out. I just had a look at your site but I cannot replicate the error you describe. Your site is up and working for me without any errors.
Do you still experience the issue?
If so, could you please try to clear all cache and cookies in your browser to make sure you see an up to date version of your site.
If this doesn't solve the problem, can you please let me know which browser you use, where you are located and send me a screenshot of the error, so I can better troubleshoot this?
