Select cachegrind file, hit update but produces no output.

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Install xdebug in MAMP on OS X
2. Produce a cachegrind file from xdebug
3. Choose cachegrind file in webgrind and click update

What is the expected output? What do you see instead?

I expect to see the processed output in webgrind. Instead a box flashes up
saying "Loading..." then disappears quickly. There is no processed output.

What version of the product are you using? On what operating system?

Using the 1.0 release on Mac OS X using MAMP and xdebug.

Please provide any additional information below.

I've checked and tried various different output directories in the config
file but it makes no difference. I've checked the write settings on the
storage directory and its world writeable. Any ideas to make this work?

Thank you for the bug report. I have just tested with MAMP on my computer and I 
am not able to reproduce the 
problem. So I think I am going to need more information to be able to help you.

It would be great if you could firebug or something similar to view the body of 
the ajax response received when 
clicking the "update" button. If that response contains PHP errors it would be 
a great help if you could post the 
error messages here.

I ran into this issue, as well. It turns out that php didn't have write 
permissions on the output directory, so 
webgrind would show the load message and then immediately fail. Giving everyone 
r/w access to the output 
directory fixed the problem.

Thank you for the comment Bob.

We should add better error handling to the system. It is on our todo list.

don't forget to activate json.so module in PHP...

Have installed json.so
Cache files are present and .webgrind file is created in output directory 
(Indicating that write perms are OK)

However I still get the blank screen when trying to load a logfile in both IE 
and 
FF3.5

As mentioned above webgrind needs better error handling. If nothing happens 
when you click "update" this will 
almost certainly be the result of a misconfiguration error. You should be able 
to see the PHP error in either the 
XMLHttpRequest response using firebug, or directly in the apache error log.

Could you please try to locate the error and post it here, then we will try to 
help you.
