Eduardo, here is a backport of the patch to 0.106.*
http://fisheye.openacs.org/changelog/OpenACS/?cs=oacs-5-4%3Agustafn%3A20110211081335This patch should work for you (i could not test it here). However, in general i would certainly recommend to upgrade; check, if you got an error during running the upgrade scripts (for every upgrade, you see a message "-- upgrading to" in the error log). Check, if upgrade worked correctly. I might be able to connect to the internet later this day.
