first thanks for your brilliant work on Restler, I am using it for some labs at the University and so far it works like a charm, really simple and elegant framework!
I've been using Restler 3.0 RC4 successfully until I updated to RC5 today. Now I'm having problems with the HtmlFormat. Whenever I try to access any of my web services that return HtmlFormat or try to enter the API Explorer, I'm getting a HTTP 500, "Unable to create cache directory /home/xxxxxxx/public_html/concrete/api/cache/php
" . Also, I see a "Warning: mkdir() [function.mkdir]: No such file or directory in /home/xxxxxxx/public_html/concrete/Restler/vendor/Luracast/Restler/Format/HtmlFormat.php on line 367" .
Do you have any idea of what could be happening? In the upgrade, I just replaced my Restler framework folder with the RC5 one, without any changes in my API itself.
I would appreciate any help. Thank you!
