Too Many redirects after the 4.4.1 WordPress Update
After the latest update; some WordPress sites had an error on their home page: Too many redirects. It appears the cause is mixed case URLs.
The websites affected had :
1 – WordPress version updated to 4.4.1;
2 – Using pretty urls
3 – Urls on Settings with Capital and Lowercase.
The Solution? go to Settings > General and make sure your siteurl and home url are only using lowercase characters.
