(35) error:14094410:SSL routines:SSL3_READ_BYTES:sslv3 alert handshake failure

[addlink]

Well, I did my best, still fails, now worse than ever.
went to paypal_curl.php, line Curlopt_sslversion => 3, placed // at beginning of line, saved, uploaded to the zen cart store files, went to my store, attempted to place an order, went to "continue to checkout" and now got a blank screen, the fix apparently doesn't work. Now any ideas? Help please. I'm not a programmer.
Thank you.

What software program did you use to edit the file? It probably mangled the file, and that's causing PHP errors, hence the blank page.
Since you're running v1.3.9, in your /cache/ folder (access it via FTP) you'll see myDebug-xxxxxxx.log files for all PHP errors. The file created when you got that blank screen will also contain the actual error message of the problem that's happening. Post it here.

You said your site is running v1.3.9f

Here's the v1.3.9f version of paypal_curl.php with the POODLE/SSLv3 fix applied. Unzip it before uploading to your server.

(If you're not using the Linkpoint module, you don't need to update any files for it.)
