Excuse me, This should be home page edit not news... When I click to edit the content of the home page the above error happens...

This is not just one site running 10.46 its two as I just checked and the condition exists on both sites giving the same error only on the home page edit...

It is NOT occuring in V11 version.

Yeah this is happening on another client site of mine as well. It's an infinite loop in diff / the revisions system when trying to process changes made to the page. It's beyond my ability to fix since it deals with very complex code. Delegating to Chris Graham.

I also had some issues with diff when editing content, so can confirm. I turned off revisions to counter it.

I may try to port the v11 version of the diff code to v10 and see if that works since the diff code was heavily changed in v11 (and seems to work fine).

Chris is going to be unavailable for several weeks so this may be the best option for now.

Additional information: Does not seem to matter what is on the home page, so the default content is not causing it. The client of mine who has the same issue has a completely different comcode page for the home page than what comes by default in v10.

Can someone confirm (or not) if this happens only on the home page of the welcome / default zone? Or does it happen on the start pages of other zones as well?

It appears to be the default/home page all others function correctly on my tested sites.

Ported v11 code to v10 to resolve this issue. Cannot generate a hotfix so will make a patch version instead.
