    Thanks so much Samboll. That was exactly it.

    @ babysenkids and owzzz or if anyone’s still wondering:

    It took me a minute to figure this out as well. It is a bit confusing when you see 4 line numbers telling you there’s a problem and none of them are php<? lines, but if you look at the parenthetic ( ) portion in the error message before it comes to stating the line number, you will probably find that all the different line numbers in referenced files, refer to just one “(output started in… FILENAME.php: line# xyz)”. That file all the lines will have in common, and that line number is likely to be at the end of the file. Either the ?> is missing at the end of the file, or after the “?> and carriage return to the next line”, there is not only that last line, but one or two empty lines after it.

    Three of my problems were solved by deleting the extra lines. So owzzz, instead of being your entire theme, it is likely only one or two files within it.

    Hope this helps clarify. Thanks again Samboll!!
