Hey @Jorihlen – there is a known issue in 5.5.2 that hasn’t been fixed:
Known issue: Apache and PHP 5.6 will result in the site showing “No input file specified.” While this limitation may be frustrating, we did not want to hold up the release. In the meantime, you can continue to use PHP 5.6 with NGINX. We hope to have a fix for this soon!
You might try a different version of PHP.
If that doesn’t work, can you please provide your Local Log? See this Community Forum post for instructions on how to do so:
