The wiki recently upgraded to MediaWiki 1.34. Aside from the trouble we had upgrading to this version, the issues are the same as in the MediaWiki 1.30.

Uploading Files
This remains an issue. Previously, gallery cells that had filenames but no image uploaded were 'clickable to take you directly to the Upload page, this is no longer the case but we know there is a solution out there and our mission before upgrading further is find out how to do this. See earlier notes: 1.30
Upgrade Issues
Moving to this version of the wiki was painful. We tried first from 1.31 to 1.35 but that did not work, then we backtracked to 1.34 which also failed when applying the upgrade script. The errors related to certain early user accounts, spammers we had blocked and deleted back in 2010, and 1 genuine user account that was deleted per request back then and then recreated under the same name. The error log suggested running a php script to fix the bad data but this required command line access which we don't have; our only option was to manually "fix" the data - there were only a few records, maybe 60 in total, but identifying them and safely fixing them was quite time-consuming.
Next update
The next "easy" update would be to MediaWiki 1.35 which is Lifetime Support version (LTS).
