if an existing zabbix configuration is updated (from 1.1.7 to 1.3.8), there are a couple of possible minor problems with web frontend :
1. if last configuration item used is non-existant after upgrade (like bulkloader.php), configuration is not accessible - link points to nonexistant file, and only error 404 can be obtained;
2. after an upgrade, "general" configuration component does not work - "Warning. Incorrect value for [config]".
this seems to have the same reason as number 1. - switching configuration component at the right hand dropdown menu works nicely and this error does not come back.
edit :
so that it's clear, frontend itself is a clean subtree, no leftovers from the old one; db was successfully upgraded using supplied upgrade sql file.
