I recently came across an issue where I was unable to open ‘Site Actions‘ on one particular SharePoint 2010 page – I was halted by the following error:
‘An error has occurred with the data fetch. Please refresh the page and retry’
A quick, simple fix was to remove the Gantt Chart Web Part from the page, then re-add and the problem was solved. But what has caused this issue?
The SharePoint 2010 Farm I was working against was fully patched to February 2012 CU, but had recently been updated with the April 2013 SharePoint Foundation security update:
I raised this with MS who were unaware of this issue, but successfully replicated the problem to one of their test environments. (which is always a relief as you’re otherwise left pondering ‘why me’?)
Patching the SharePoint Farm to the full April 2013 CU patch level permanently resolves the problem.
