What I did was follow the instructions for upgrading and I deleted all of the existing files and replaced them with the files that I downloaded for the 1.6 version and then installed it like before and chose upgrade from previous version and followed the instructions but I'm getting errors at the last step because its telling me this error:
The installer couldn't update the ConnectionStrings.config file on your server. This may be caused by limited file system permissions. Please open your ConnectionStrings.config file manually in Notepad and add the following line inside the <connectionStrings></connectionStrings>:
The problem is that I have the exact same connection string that it includes in the connectionstrings.config file but its telling me this when I try to click next:
The connection string you added doesn't match. Make sure, the connection string is correct.
How can I fix this?
