I'm running into an "Unable to open the test log" error in Test Manager, sometimes right after the log has been generated from a Robot script, and sometimes a day or two after the test has been run.
Maybe it's just a corrupted file, but it seems to occur rather frequently, and I can't seem find anything on the RDN about it. Can the file be recovered somehow?

Delete the logs in the build folder of your application and then try again.
A highly advanced bug is indistinguishable from a feature.
