Item12290: Can't call method "setArchivist" on unblessed reference

I'm running FosWiki 1.1.5, Tue, 10 Apr 2012, build 14595, Plugin API version 2.2 on a cPanel CENTOS 5.8 x86_64 VPS instance.

I upgraded the VPS system software because of this cPanel post: http://cpanel.net/important-11-30-11-32-11-34-cpanel-whm-updates-available/

Now, I get this error after logging in:

"Foswiki detected an internal error - please check your Foswiki logs and webserver logs for more information.

Can't call method "setArchivist" on unblessed reference"

The error goes away when I disable DBCachePlugin.

I upgraded DBCachePlugin to the latest version, and also deleted the DBCacheContrib cache, but I still get the error when DBCachePlugin is enabled. The site seems to be working OK without the DBCachePlugin enabled, but I want the FosWiki team to know about this issue.

I think it has to do with the new cPanel Perl Storable module. Here is some of the verbage in the cPanle post listed above: "The Perl Storable module provides support for serialization and deserialization of Perl data structures. In cPanel & WHM this functionality is used for caching data to disk and transferring data between processes. In many areas this caching and interprocess communication crosses privilege separation boundaries. A local malicious user could use this behavior to inject code into serialized data structures, thus allowing for code execution and possibility of privilege escalation."

I plan on upgrading to Foswiki 1.1.6 in the next few weeks, but this seeme to be extension specific.

Thanks in advance FosWiki team, FosWiki is awesome FOSS!

I've experienced the same problem and found out that the latest Storable (http://search.cpan.org/~ams/Storable-2.39/Storable.pm) is failing to store blessed objects, or at least to retrieve a blessed object as it was before. The main object been stored isn't blessed anymore, as well as none of the sub-objects: they are all plain hashes once retrieved.

Downgrading Storable to 2.29 cured it for me.

Michael, downgrading Storable to version 2.29 worked perfectly. Thank you very much!
