First off I have tried clearing my browser cache but that didn't solve the problem.
I have some previously shared folders that were created a long time ago, screenshot - shared-folders.jpg.
I have not needed to add any new shared folders until now and the process now fails.
I hit the Add button and fill out the table for a new shared folder called d1-movies, screenshot - newsharedfolder.jpg, then I hit the Save button. The new shared folder now appears in the table, screenshot - newsharedfolder2.jpg.
Then I hit the Apply button and an error popup is thrown, screenshot - error1.jpg. When I press the Show Details button I get screenshot - error2.jpg.
All I can do at this point that does not throw any additional errors is revert the changes.
Any ideas?
