My website has 500 error on landing page since 09/01/2021 without any reason

Finally prestashop.com come back to business.

My website suddenly down with 500 error without any reason. Nothing had been changed. The log error message says:

[01-Sep-2021 09:57:14 US/Eastern] PHP Parse error:  syntax error, unexpected 'require_once' (T_REQUIRE_ONCE) in /home/home/public_html/domainxx.com/modules/authorizedotnet/authorizedotnet.php on line 1

I have been trying to figure out by debugging for three days but no luck!

Anybody can help? Or anybody has the same issue?

Thank you

Thanks for this advice

But there is no way to disable the anthorizedotnet.

Because the dashboard cannot access the module as well.

What is your suggestion?

 

Thanks

Thank you so much ndiaga.

It helps, now do I need reinstall the Authorize.net plug from the dashboard - > modules?
Do you think my issue is related to prestashop.com down? It happened on September 1st afternoon without any reason. 

Again, any suggestion is helpful!
