Thread:Project:Support desk/Watchlist error after upgrade to 1.18.1/reply (6)

The same issue occurs on MW 1.19.2 (Vector, Mozilla + IE). Sure I could set $wgAjaxWatch to "false", but I need it to be set to "true" in order to run Extension:CategoryTree. There is a slim chance that in my case, this is related to a recent upgrade of SMW from 1.8.0.3 to SMW 1.8.0.4, but that doesn't seem very likely.
