WordPress Site Troubleshooting and Optimization

My WordPress website has been experiencing issues. When users click on our Facebook Ads, they encounter a 'redirected too many times' error on the landing page. Additionally, the website's speed has been subpar, despite previous optimizations. I need a technical expert to diagnose and fix these issues.

Ideal skills and experience:
- Proficient in WordPress troubleshooting and maintenance
- Experience with Facebook Ads landing page optimization
- Strong background in website speed optimization
- Proven track record in resolving redirect loop errors
