Ever since upgrading to 1.2, sparklines fail to be generated.
I’m suspecting a permission issue somewhere, but I wasn’t able to pinpoint it.
Which folder needs which permissions for sparklines to work?
From reading the FAQ, it seems one reason they cannot be displayed is if GD doesn’t work anymore, but based on various tests, it seems GD is working just fine.
In the text editor, I see something that looks like a PNG, but with a lot of extra characters. It’s similar to what you see with a utf-8 conversion gone bad.
It starts with
ʐNG
instead of the usual
‰PNG
Could be Firefox that saved it in a weird way though…
Edit: Similar file when saving with Chrome
I deleted both the files in tmp/assets and in tmp/templates_c, but although new files are generated, the browsers still complain about them.
I’ll recompile PHP just to be sure, but this wasn’t happening before 1.2, so I’m trying to figure out what changed besides Piwik.
My problem is that there is nothing special in the logs…
All I see is that Apache is complaining about a missing favicon.ico at the root level, but piwik is installed in a folder.
