I checked the site. It is an internal error. If you didn't change any source code editing or other changes like installing plugins or new themes, please contact your hosting service provider and make sure this is not an issue with the provider's servers. If it is not a problem with the hosting provider, please accept my support offer. Then we can contact privately and you can share hosting controlpanel details to me privately. Then I will check the codes and database and can fix the errors.
Thank you, ***** ***** own time and inform me your decision after discussing with your boss.
