@kitz:
Many thanks for the reply, very much appreciated especially under your current circumstances.
Just checking that you have php installed?
To my complete embarrasment, no.
Just shows how much I know, apologies for my ignorance on the subject.
Apache2 and php now installed on my RPi 3B running "stretch" and access tested from local & remote web browsers.
However, still struggling with the same error, I believe it's because I am not placing the live files in the correct location.
The webserver files are by default located @
/home/pi/.dslstats/webserver php default file directory is
/var/www/htmlTotally confused as to where the history.php script expects to find the live data files which I believe is now the issue.
I appreciate that a third party routine will need to be deployed to refresh the live data files at a chosen frequency to provide historical information.
