Sorry Heiner due to the issue I had it was not possible to see any page for LMS so without being able to see anything it was not possible to copy the log .
As indicated above I have created a clean new download of the image and loaded that . Set up was as expected and LMS and Material Skin are both working again as they had been for weeks after my original download and set up .
Things are back to normal again but as this is a new install I am not able to go back and review what happened with the previous install and give you the feedback you need to see what happened .
Will just use the current install and hope the issue was just a one off .
