Yesterday I have issues updating Repository cache after uploading new .PRPT ‘s to my solution repository on a BI Server version 3.6 .
After a while I noticed that reports which failed had éá and latin characters so I turned it into ASCII ea and all worked correctly.
Second problem was to open on my Pentaho User Console, reports with + char on its title. The solution was to avoid the using of this type of strange characters.
Hope you help
