Fatal Error!

Fatal error: Uncaught UnexpectedValueException: The stream or file "app.txt" could not be opened: failed to open stream: Permission denied in /home/treehouse/workspace/vendor/monolog/monolog/src/Monolog/Handler/StreamHandler.php:87 Stack trace: #0 /home/treehouse/workspace/vendor/monolog/monolog/src/Monolog/Handler/AbstractProcessingHandler.php(37): Monolog\Handler\StreamHandler->write(Array) #1 /home/treehouse/workspace/vendor/monolog/monolog/src/Monolog/Logger.php(336): Monolog\Handler\AbstractProcessingHandler->handle(Array) #2 /home/treehouse/workspace/vendor/monolog/monolog/src/Monolog/Logger.php(391): Monolog\Logger->addRecord(300, 'Oh Noes', Array) #3 /home/treehouse/workspace/index.php(10): Monolog\Logger->addWarning('Oh Noes') #4 {main} thrown in /home/treehouse/workspace/vendor/monolog/monolog/src/Monolog/Handler/StreamHandler.php on line 87

When wrote 'Foo' index.php worked, then I change text on the 'Oh Noes', so then I see that Fatal Error. What I need to do?

Simply delete the app.txt file and it seems to work again. A new app.txt file will be created when you run the program again.

Thanks ! it works!
