Hi guys!
Some I’ve been creating webapps with Yii for quite some time now and I just created a free Heroku account but, I’m not even able to run a normal webapp one can create with Yiic. Does anyone has a Yii webapp hosted in Heroku? some advice to give??
Thanks!
Almost forgot!
It throws me this error:
Application runtime path "/app/www/protected/runtime" is not valid. Please make sure it is a directory writable by the Web server process.
Does someone knows what it means?
Heroku has read only file system. You can only write to tmp.
Good luck 
Were you able to use Yii on heroku?
I actually just set up my system on heroku and ran into that same problem. I wrote a post about it, I hope it helps. I’d be happy to answer any questions
