I keep getting the following error message each time I try and use the Publishing Service box: ?:0:attempt to index field 'exportSettings' (a nil value)
See image below
I have disabled all the plugins except hard drive. Each time I click where it says 'Set Up' the error window pops up.
I can go to the publishing manger but I am unable to configure the Hard Drive settings - whenever I save I still get the 'Set Up...'
I have tried deleting the preference file and reinstalling Lightroom but the same thing happens
I ended up uninstalling Lightroom plus all additional LR files and folders and reinstalling - this fixed the problem
good to know that you were able to resolve it.
