WordPress AWS Migration Issue Resolution

Job ID: 37999924

Budget: $10 – $30 AUD

I'm here because I recently migrated my website to AWS and I'm now encountering some issues. My WordPress website, currently on version 5.4, is presenting a 404 error and deprecated warnings. Sadly, I do not have access to the original server the site was hosted on before migration, and I'm unable to specifically point out if any plugins or themes may be causing these warnings.

This project requires a skillful WordPress expert who is familiar with:
1. AWS migration
2. Troubleshooting for WordPress version 5.4
3. Identifying and resolving 404 errors and deprecated warnings
4. Investigating possible plugins or themes issues

Ideal candidates should have proven experience in troubleshooting WordPress issues, specifically in a post-migration context. AWS proficiency is a big plus because of the platform's involvement. I welcome suggestions and look forward to remedying this situation with your help.
