I just installed xampp with php 7.0.4 and a fresh cakephp 3.2.6. I did a lot of research and everything I found shows that they are compatible.
However as soon as I go to open the application with a browser, cake replies with an Internal Error.
The only pointer as to what to do is that xampp logs the following in apache error.log:
PHP Fatal error: Uncaught TypeError: Argument 1 passed to Cake\Error\BaseErrorHandler::handleException() must be an instance of Exception, instance of Error given in D:\Xampp\htdocs\cakephp\vendor\cakephp\cakephp\src\Error\BaseErrorHandler.php:153
Stack trace:
#0 [internal function]: Cake\Error\BaseErrorHandler->handleException(Object(Error))
#1 {main} thrown in D:\Xampp\htdocs\cakephp\vendor\cakephp\cakephp\src\Error\BaseErrorHandler.php on line 153
I tried php 5.6 but it still shows the error in the log.
If that's the error that you are encountering, then I'd doubt that you are using CakePHP 3.2.6, as line 153 is in the middle of a comment
https://github.com/cakephp/cakephp/blob/3.2.6/src/Error/BaseErrorHandler.php#L153
PHP7 errors are handled since CakePHP 3.1.5, so check your CakePHP dependency, and make sure it's actually up to date.
