Mark,
I have just updated from version 1.48 to version 1.52
installed php-intl extension
I backed up my rompr folder, deleted everything in it, then restored my albumart and prefs folders
then unzipped version 1.52 into it
then restarted my server
everything seems to start up ok and albums appear to play correctly
but none of my personalised radio stations appear to work they all return "Didnt find any tracks"
I have tried deleting and recreating a station but it does not make any difference
as an example one the stations contains the following rules
Genre does not contain xmas
year is less than 1970
year is greater than 1959
not surprisingly the station is named 1960s
let me know if you need any more info
Tim
