I'm getting the following messages immediately after install.
Apr 24, 2019 1:48:06 PM hudson.ExtensionFinder$GuiceFinder$FaultTolerantScope$1 error
INFO: Failed to instantiate optional component com.cloudbees.hudson.plugins.folder.properties.FolderCredentialsProvider$FolderCredentialsProperty$DescriptorImpl; skipping
on Ubuntu 16.04. This seems to be preventing the Multibranch Pipeline plugin configuration page from opening. It has been an hour since I went to the page. Reloading does nothing.
Help please.
