Forum .LRN Q&A: Re: File Storage Error on Arch Linux
just to avoid possible misunderstandings: when I talk about "package manager" in OpenACS, I refer to the one you can access via e.g. /acs-admin/install/ on your installation.
There, you can find a button to upgrade you packages from repositories. You should be able to find new versions for your 5.9.1 packages.
Reinstalling from a new 5.9.1 tarball will not work in this case, as fixes for released packages are backported and distributes only via the package manager.
Hope this helps
