After install I am getting error "error: cannot create log directory"

[datsnl]

Hello,
I wanted to try SunCAE and installed on my virtual private server. Installation went well and I can see that it installed everything from the script.

Now when I upload the sample.step file, it is giving me "error: cannot create log directory" repeatedly.

Either

1. Make sure the owner running the web server is the same as the owner of the data directory, or
2. Give 0777 permissions to the data directory

We should add a "check" page that is shown the very first time someone enters into a fresh installation that should check all the dependencies are there, that the permissions are fine, that the web server is sane, etc.

Do you guys think you can help us with that?

I would like to add that the same SimplePart.step works on demo SunCAE website. [image: image.png]

The images have been lost, but I think that error is coming from a missing library.
I'll get back at you ASAP.

This is on my website

This is on demo site

Can you check if the file has been uploaded or not? There should be a file named original.step somewhere inside data/root/cads/hash .
Maybe the file was not uploaded, it has zero size or it has wrong permissions.

Please let me know. We should add a check on SunCAE's side for all these possible issues so we show a proper error message.

If I'm not mistaken, it should be in data/root/cads/9186d20ca41dff65ae6ee1494133b003.
Can you post the output of ls -lt in this directory?
