After updating to 2.6.0 I am not able to correctly access the logs in WebAdmin, eventhough logs are present in the file system. There are no obvious errors in WebAdmin itself, but selecting access-logs that are known to contain entries (by inspecting via editor from file system) are shown empty.
It turns out that WebAdmin itself throws exceptions that are logged.
WebAdmin seems to search for consecutive daily logs that might not be present for the given day because of low activity. It then seems to throw, this leads to the erroneous behaviour in the front end (e.g. empty display of the top log or display of wrong content).
Below is the partial content of todays WebAdmin-Log (the logs not foun are indeed not present as the server is not overly busy used). if "holes" are filled with faked empty log files, the next missing file is "reported":
