I'm not sure how it happened, but the same user was able to react twice to one of my posts here on this forum:

Has this happened recently on the latest release? If so, not really a good test case at the moment, I'm afraid, but please let us know the example if it happens that way in the future.

It happened today and we are on the latest release with all patches applied.

I have added some notes in the clients area.

As you have a custom theme and third-party applications/plugins which interact with code surrounding this, I would recommend starting by ensuring these are compatible with the release you're on.

The issue is not new but happens randomly that`s why we haven`t reported that.

if it helps to investigate I have added another link to the client area that I found with a double reaction.

You would need to check each author's independent site to see if there have been any releases. Additionally, simply because there has been no release, does not mean it is compatible. Please note this would also impact plugins as well.

I have already done that for both items .

I would take note of what I edited here as well. The author would need to state compatibility. 

Ok I will double check and I will report back.
