Thread:Project:Support desk/Internal error message

Dear all,

We use a MediaWiki at openDemocracy (http://wiki.opendemocracy.net/).

We recently transferred our site (www.opendemocracy.net) and the Wiki to a new server. Since doing that we have got the following internal error message whenever we try and save edits to the Wiki. I just wondered whether anyone had experienced the same thing and had any recommendations for action?

Internal error Detected bug in an extension! Hook ConfirmEditHooks::confirmEditMerged failed to return a value; should return true to continue hook processing or false to abort. Backtrace:
