function.session-start issue using WordPress e-commerce plugin
<p>Trying to get an e-commerce plug-in to work in WordPress. Totally fresh install; this is my second try. Same error message "line 17." I've read the other posts which suggest moving "session_start();" to the top of the file. Tried this. "Fixed" error message, but "add to cart" function of the plugin fails once I try the fix everyone recommends. Am not super great with php, css, html am great. Sorry not sure I know how to add code to this post. Thanks!
