Project description:
"need an experienced WordPress developer with strong PHP upgrade troubleshooting skills to resolve compatibility issues and support an upcoming server migration.

Current Situation

We are moving several WordPress sites to a new server running PHP 8.1–8.4.

Some of our existing sites still run on PHP 7.4, which is causing breakage due to plugin/theme incompatibility.

What We Need
1. Immediate Fix (Today)
Two WordPress sites are currently broken after being placed on a PHP 8+ environment.

Your role:
- Diagnose the PHP incompatibility issues
- Fix plugin/theme errors caused by the migration
- Ensure the sites are live and working after migration

Note: One of these sites uses a WordPress multisite network, which may require extra attention during the PHP update.

2. Migration Standby (Tomorrow)
- We have three additional WordPress websites being migrated tomorrow.
- We need you on standby during the migration to immediately fix any PHP-related issues that may arise once they’re moved, as we have an event 1 Nov 2025.

Required Skills
- Advanced troubleshooting in WordPress
- Strong experience resolving PHP 7.4 → PHP 8.1+ compatibility issues
- Plugin/theme debugging
- Understanding of error logs & deprecated functions
- Experience with WordPress multisite

Ability to be available today + tomorrow

Additional Technical Notes
- Issues are likely due to PHP incompatibility or outdated plugins
- Some nameservers/URLs may need updating after the migration
- One site is a multisite, others are standard WordPress installs

Timeline
- Today: Fix 2 broken WordPress sites
- Tomorrow: Be on standby for 3 site transfers and fix any PHP errors in real time" (client-provided description)
