I upgraded my partners blog to 2.6.2. She uses a theme called WsWired which has always been fine. The upgrade appeared to work alright. However there is one issue in that when you go into Design/Widgets the Links widget no longer shows up under available widgets. Also the sidebar widget message states that ‘You are using 4 widgets in the sidebar.’ when only 3 actually visible due to the broken Links widget.
When viewing the blog obviously the links don’t display. If I turn on blogroll instead of links it displays however not correctly. If I swap to the ‘Default’ theme the Links widget is instantly available and if I add it everything works as it used too. Comparing the dashboard and widget php files there seems to be minimal changes from the original ones to the new ones. Does anyone have any ideas how to troubleshoot this or what the issue may be?
