Hi all,

I've been running DNN 9 (upgraded from 6) for a few weeks now with no problems. Over the weekend something seems to have happened that is causing a heap of internal server errors relating to jquery. The site itself still loads, but nothing that uses jQuery does and as such, I am unable to use the persona bar as it does not exist. Errors are below, site is public so feel free to visit if you want to see them yourself.

I've turned off custom errors and turned on debug but I can't get any error other than 500 (even on the server). Again, it's been working up until today and nothing has been changed on the server. Any ideas would be great.

Thanks,

Justin
