I'm Fairly new to perch and i keep having the same issue
Headers already sent ...
and not sure why this always happens
its always with the shop checkout i see the issue it will work first time on initial setup but seccond time (no code changes) i have header issues
ive looked for spaces, white space BOM ect and they are all fine
could it be the program i use to save the files could it be me putting code in the wrong place
would appreciate some pointers but this issues is spoiling my perch experience
