I report here because there have been several entries in the community list which are identical and which don't seem to have any resolution. See this thread http://moodle.org/mod/forum/discuss.php?d=48065

I am using 1.5.4+ and following the instructions, downloaded and unpacked 1.6+ and then carefully loaded all of the additional modules and filters that we are using in our current install. I took special care to load only 1.6 compatible modules where they were available. Some modules are now standard. I then added our theme and our config file. repacked the site and sent it to the server. Fortunately I have direct access to the server so I copied the moodle data file, exported the MySql DB, renamed the moodle folder and unpacked the new upload in its place.

I then started the web site up (externally and the upgrade seemed to be going nicely until I ran into the identical problems as outlined here. Now, I believe I have conducted a squeaky clean upgrade and have been disappointed by the failure - even more so to find no answer here.

I am now back at version 1.5.4+ but am under pressure from my boss to get 1.6 running before Monday (school hols now) when the site will be very active again.

What can I do differently to make this work? Full error report attached on original community request for help but see link above..
