My ISP has upgraded the scripting language the query store uses and consequently the script no longer works.
It was decided to move the Query Store data into the Downloads area.
There are now separate sections for reports, queries and text schemes and the added advantage is that there is now a search option included.
The biggest problem with this is that there is currently no upload option, but I hope to put one in place in the near future. Any members who have their own web space can upload files to their own web space and add in download link the downloads section.
I will be on holiday from the middle of this week so will be unable to progress the problem further until my return.
