I've picked up Workbench / DocumentationTools again to add some new tutorials. Everything was going fine until I tried to use the "Link to Tutorial" button in DocTools. Didn't work, and I got some error messages in the console:
StringMatchQ::strse: String or list of strings expected at position 1 in StringMatchQ[$DocumentationDirectory,*/]. >> StringMatchQ::strse: String or list of strings expected at position 1 in StringMatchQ[$LinkBase,|Whitespace]. >>
The neighboring B-button was even worse. Any ideas on what happened to my previously working setup? I'm using Workbench 10.1.822 and Mathematica 10.0 to make documentation (12.1 is my daily driver) on MacOS 10.14.6.
