After much back and forth with my hosting service provider trying to troubleshoot this problem, I got this message first:
"So, I have checked error logs for your website in its Web Options section and found the following error:
[Fri Dec 05 03:12:16 2014] [error] [client 91.217.144.253] Premature end of script headers: php53.cgi, referer:
n-retrospect.com/index.php/cb-profile-write
I'm forwarding this ticket to our administrators to check the issue for you and found if there is something server related. Please wait for our reply."
I received this response today:
"Let me please inform you that according to the reply of our system administrator, there is no issue with the server at the moment and your account is fully operable. Our support team have tried to enable different PHP settings and versions for your web site application but unfortunately it didn't help. As we have checked this issue is caused by the plugin "Community Builder"...We would like to recommend you to reinstall this plugin or look for another plugin with the same functionality."
I will try re-installing CB and see if that makes a difference.
-- I tried re-installing but didn't seem to make a difference. Using Filezilla, I looked at logs and found the following- The IP address 98.234.78.43 is my own current IP address:
