I may have found a solution here: https://bx.com.au/blog/2013/02/godaddy-hosting-pageok-message/
Viewing the page source for your Instructors
page, I see the following:
<!-- pageok -->
<!-- managed by puppet -->
<html>
<head>
</head>
<body>
<pre>pageok</pre>
</body>
</html>
…and on your home page, I see this above your DOCTYPE and opening HTML tags:
<!--23d23d4reds122wqs-->
So the problem seems to be with your hosting account, although it may be triggered by the plugin if you are attempting to access a CSV file that is located on a different domain. (I’m not sure that is correct, just a hypothesis given the limited information I am working with here.)
I would recommend following the instructions in that article, which are as follows:
1. Make sure you have the domain name set up in your hosting account
For every host entry (“A” record) that you configure in DNS, you must set the domain name up in your hosting account. To do this:
- Go to your hosting control panel
- Select “Hosted Domains”
- Add the domain or subdomain
2. Make sure the entry you created in the “Hosted Domains” section of your hosting control panel is not still pending setup.
When you add a domain to your hosting account, it can take a LONG time. Up to 24 hours, in fact. To check if yours is pending:
- Go to your hosting control panel
- Select “Hosted Domains”
- Find your entry and check its status. If its status is “pending” then you are going to see a pageok message.
