I also get following error while click on save changes
There is a problem getting an authorization code from LinkedIn®:
array_key_exists() expects parameter 2 to be array, null given in <b>D:\xampp\htdocs\SampleEdu\wp-content\plugins\lips\otherservice.php</b> on line <b>183</b>
1:CURL error: SSL certificate problem: unable to get local issuer certificate
This may be caused by incorrect OAuth Identification, a slow internet connection or a problem at LinkedIn®. Retry in a couple of minutes if you did not change anything. Read the posts at LinkedIn REST forum when the problem persists.
