Wordpress website updated php now won’t load

I require assistance troubleshooting a PHP compatibility issue affecting my WordPress site following an automatic platform update. The site was functioning correctly until recent PHP updates were applied via my hosting provider, now upon loading I receive a critical error. An investigation of the server logs and code is needed to determine what changes may have caused this regression. The successful freelancer will have strong PHP and WordPress debugging skills to methodically diagnose the root cause. Example troubleshooting steps include reviewing updated PHP modules for conflicts, checking for deprecated functions/methods, verifying server configurations and more. Once identified, the issue will need to be resolved through code modifications, configuration tweaks or a rollback if needed. Experience solving similar WordPress and PHP compatibility problems post-update is essential. The goal is to have the site back online as quickly as possible once again.
