This plugin worked like a charm and identified a problem that other plugins had missed.

I had a slight problem getting it to run on one particular site but after contacting the developer, I increased the memory_limit and got it running.

The support from the developer was first class – They even logged into one of my sites to help identify an issue.

One tip I would give is, give the plugin time to initialise – It can take 3 to 5 minutes (in my experience) to start – but it was worth the wait 🙂
