Hi,
I have a site running version 2015.1.225.1 that has worked up until 1st January 2021. Now I am getting several javascript errors related to
Telerik.Web.UI.WebResource.axd
with the following errors:
net::ERR_ABORTED 500
Any suggestion on what it might be?
I have not done any changes to this code for many months (perhaps a year) as we are moving our customers over to a newer version (which means I have little to no knowledge how to find and fix this problem). We still have a few customers left on this site and they are now unable to do their work because of it. All I need it a quick-fix/workaround that might work for the next 2 months.
