Hi,
You will notice that the section of the path (core/class) has been repeated. There is obviously a 'replace' statement that is getting confused with the forward slashes and the backslashes.
Also, in 'defines.php' there is a section which referes to 'Pear'. It includes a line of code that can be commented (either in or out) if you use Windows. This is the only mention of Windows that I can find in the code and App State say that they develop on *nix systems and don't support Windows.
It seems that we need to search the code for the backslash anomalies and correct them. The problem being is that if, like me, you want then to upload to a *nix host, you have to go through and undo the lot
We need a function that will do this all in one go and, possibly, detect the OS. Beyond me I'm afraid but I live in hope.
Best wishes,
Alan ...
