XF 1.4 openbase_dir issue


Active member

I own a live forum at /home/e-smith/files/ibays/forumasus/html/www running 1.1.3

I am setting up a new forum next in this folder :
/home/e-smith/files/ibays/forumasus/html/forum running 1.4.3

I originally set a /tpm dir to work with my live forum and all is working ok :

When i try to upload a ressource, image, avatar etc with the new forum, i get this error :
file_exists() [function.file-exists]: open_basedir restriction in effect. File(/tmp/xfLgLCE3) is not within the allowed path(s): (/home/e-smith/files/ibays/forumasus/:/usr/share/pear/:/bin/tar)
Does 1.4 manage /tmp dir the same way than 1.3 ?

We set /tmp directory outside /html directory for security reason and avoid that session could be stolen from other /html services.

Anyway to fix this issue is the most welcomed.

Kind regards

Env : PHP Version 5.3.3

You generally want to add /tmp to the open_basedir at least to deal with uploaded files for example or other temporary files.

In this case, it looks like it was a file created by XF which probably means the attempt to create it in the internal_data/temp directory failed for some reason. That would likely be PHP falling back to it.
