+## Why has the *Error* class been renamed to *Problem*?
+
+The project was written in PHP5 times, but with the release of PHP7 it's not possible anymore to name a class
+"Error" as PHP itself has a internal Error class now. Renaming was the most simple solution, compared to other
+options like "ErrorController" etc. which would add new problems like uppercase filenames etc. (which will not
+work properly on some setups).
