Hi all,

We had the following warnings appearing today when we tried to install joomla.
When I cam back to work on the site on my computer tonight, it was no longer there and all seems to be working well.

Again, I am a designer head, rather than a code man, so get easily confused with some of these warnings.
Can anyone explain what this was and should I be wary of continuing with the current installation.

Cheers,

Ant. S.

Check your permissions on the /tmp/ directory:

ls -ld /tmp

It should be rwxrwxrwx (I.e. owner, group and world can write to it).

If not, change it:

chmod 777 /tmp/

By default /tmp is writeable by everyone so it is possible someone or something has changed the write level.

The initial failure appears to be a permissions problem when starting a new session or resuming an existing one. The permission in question could be the rights on the /tmp directory (should be set to 755), or maybe a transient failure during PHP's session_start() function. You were installing at the time so lots of weird stuff could have been going on.

About the only thing you can do is check the permission setting on the /tmp directory. If that is at least 755, then check back through the Apache error log to see if there is a pattern of recent permission or system problems. If not, the problem was transient anyway so just let it go, but keep an eye out for a few days for any repetitions.
