Twitter signin not working but all others are?

I found the error in a plugin file: /wp-content/plugins/addthis-social-sign-in/includes/OAuth.php

If you edit the code there is white space after the ?> closing tag at the end of the code. This fixed it for me and I was getting several errors.

Why yes, it worked.

There where blank lines after the ?> closing tag at the end of the code.

Deleted them, and saved. Then it worked.

Thanks.

Has anyone else hit this issue?

Just installed. Facebook & Google logins worked smoothly.

I fixed the Twitter error by deleting the white pace as mentioned above. Great find joivmaco. Thanks!

Ditto on the “Great find joivmaco. Thanks!”

UN-fortunately, I also ticked the check box for the Yahoo sign-in…

Got this error message:

=-==-=-=-=–=
line 172 says:
if (curl_errno($curl)) {
throw new ErrorException(curl_error($curl), curl_errno($curl));

and line 42 says that:
* The library requires PHP >= 5.1.2 with curl or http/https stream wrappers enabled..

Some webhosting companies do not enable curl unless you ask them to.
Obviously the case here.

Don’t see anywhere to enable http/https stream wrappers…

So for now I “un” ticked the Yahoo authentication… Shame

OH YEAH – the file

/plugins/addthis-social-sign-in/includes/openid.php

had NO closing ?> at the bottom of the file.

Well, if I get some more time to look at this I’ll update what I’ve learned ??
