Need someone to fix my Wordpress-Website after PHP Update

-/ What error do you currently see when opening the sites: blank page, 500 error, PHP error message, or something else?

-/ Do you have access to the hosting control panel, website files, database, and PHP error logs?

-/ Also, apart from restoring the websites, are there any important functions I should specifically test such as forms, bookings, payments, user accounts, or admin functionality?

- When you say that "nothing works anymore," do the websites show a completely blank page, a PHP/WordPress error, or do specific features stop working?

- Are both websites using the same WordPress theme and plugin setup, or are they different installations? Were any plugins or the theme updated at the same time as the PHP version, or was the PHP 8.4 upgrade the only change?

- Are taibasurf.ch and taibasurf.com separate WordPress installations, or is one domain a copy/multisite/redirect of the other?

Hi Andrea,

I noticed most of the discussion is already focused on hosting access and error logs, so I won't repeat those questions.

Since you have a full backup from immediately before the PHP 8.4 update, could you confirm one thing: were both websites fully working immediately before the PHP change, with no pending WordPress/theme/plugin updates or existing errors?

If they were, that gives us a very clean point of comparison and should help isolate the PHP 8.4 incompatibility without unnecessarily changing the existing sites.

We’d be happy to diagnose and repair both while keeping the current design and functionality intact.

Could you please share the PHP/WordPress error logs from the hosting?

Do you have access to the hosting panel or server where both domains hosted?

cyon doesn't actually use cPanel, so could you please confirm if you can provide my.cyon access instead?

I’ve checked the issue and the critical error is most likely caused by something that is not compatible with PHP 8.4. Do you have access to the hosting error logs so I can pinpoint the exact cause and fix it?

I can see the website is showing a critical error after the PHP 8.4 update. Can you give me access to the WordPress admin and hosting so I can trace the error and fix the plugin, theme, or code causing it?

Do you have access to the WordPress admin and hosting panel for both websites, so I can check the PHP errors and affected plugins/themes directly?

Do you have access to the hosting panel or server where both domains are hosted?
