Hi buelow,

Thank you for reporting this.

After investigation, we found out that your link in converted in this after CURL call

Temporary RedirectTemporary Redirect The document has moved here https://doc-10-60-sheets.googleusercontent.com/pub/.....

The described behavior is a feature:

https://developers.google.com/apps-script/guides/content#redirects

• RedirectsFor security reasons, content returned by the Content service isn't served from script.google.com, but instead redirected to a one-time URL at script.googleusercontent.com. This means that if you use the Content service to return data to another application, you must ensure that the HTTP client is configured to follow redirects.

What you can try is to add this code in file wp-content/plugins/wpdatatables/source/class.wdttools.php around line 205 you will find this

curl_setopt($ch, CURLOPT_REFERER, site_url());

and below that add this code

curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);

so your code will look like this

We need to test more but for now it is working in all test cases.

Sorry for inconvenience,
