[Plugin: Flattr] Capabilities check freezes up

Try opening https://localhost/wp-admin/admin.php?q=Flattr&flattrJAX=true&page=flattr%2Fflattr.php where you replace localhost with your blogs domain name of course, what is the result?
If it works, it should return something like this:

{“result”:”passed”,”feature”:”Flattr”,”text”:”connection established”}

It returns on both servers:

Warning: curl_error(): 214 is not a valid cURL handle resource in /blablabla/wp-content/plugins/flattr/flattr.php on line 148
{"result":"failed","feature":"Flattr","text":false}

The number 214 sometimes changes.

If you can, please replace lines 136 to 150 (from case “Flattr” to break; in flattr.php with the following lines:

case “Flattr” :
$retval[“text”] = “Flattr API v2”;

$ch = curl_init (‘https://api.flattr.com/rest/v2/users/der_michael’);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1) ;
$res = curl_exec ($ch) ;
$res = json_decode($res);
if (isset($res->type)) {
$retval[“text”] = “connection established”;
$retval[“result”] = PASS;
} else {
$retval[“text”] = “curl connection error “.curl_error($ch);
}
curl_close ($ch) ;
break;

and then check again please.

Did one more experiment: I moved the
curl_close ($ch) ;
from line 142 to line 150. Trying the wizard now gives me a changed result:

checking cURL curl_init
checking oAuth OAuth2Client
checking php 5.2.17
checking WordPress 3.3.1
checking Flattr SSL certificate problem, verify that the CA cert is OK. Details: error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed

Sorry, got your post above only now. Did I do what you wanted me to do? Or still need to try?

ok, thanks, please include the follwing line before the curl_exec

curl_setopt ($ch, CURLOPT_CERTINFO, false) ;
curl_setopt ($ch, CURLOPT_SSL_VERIFYPEER, false) ;

curl 7.10 apparently has other default values than versions before

The Wizard freezes again. I try the direct link, it tells me:

Warning: curl_setopt() [function.curl-setopt]: Invalid curl configuration option in /mnt/web5/51/50/5346950/htdocs/divneveci/wp-content/plugins/flattr/flattr.php on line 142
{“result”:”passed”,”feature”:”Flattr”,”text”:”connection established”}

So I remove the line with “CURLOPT_CERTINFO”, now the wizard works (tried on both blogs), Flattr shows: “connection established”.

The buttons don’t change after all tests are done – is the wizard completed?

If all results return green, the wizard can continue, if you have a yellow or red result, the wizard will not continue. Your PHP check is yellow, right? If this is the only yellow line, modify line 114 in flattr.php to

$retval[“result”] = PASS;

Yes, the PHP version is yellow. I cannot upgrade PHP, my provider has the exclusive power in these things.
What is the minimum PHP version?

If this is the only yellow line, modify line 114 in flattr.php to

$retval[“result”] = PASS;

Now it continues, but after registering the application and entering key and secret, it keeps on validating.

might be the same issue with curl close, let me look into it

Please open the following url, what is the result? replace the <values> according to your setup:

https://<hostname>/wp-admin/admin.php?flattrJAX=true&page=flattr%2Fflattr.php&flattrss_api_key=<key>&flattrss_api_secret=<secret>
