Warning: unlink(C:\Edcor\piwik090/tmp/templates_c%%9A^9A3^9A34FA06%%index.tpl.php) [function.unlink]: No such file or directory in C:\Edcor\piwik090\libs\Smarty\internals\core.write_file.php on line 44
This is the error that I am getting when the pages load
The directory that you mention has write permissions set, this is not the problem.
If you actually look at the original error, you will notice that it says no such file or directory.
This problem occurs when the Smarty compiled file does not exist on the server.
