Hello Pat

Can you please tell me which version of libxml do you use.

You should find the libxml version in your php.info file.

If the version is less than 2.7.8

In file  wp-content/plugins/wpdatatables/source/class.wdttools.php and around line 1302 find this code 

if (self::isHtml($string)) {
$string = self::stripJsAttributes($string);
}

and comment it so the code look like this 

//if (self::isHtml($string)) {
//$string = self::stripJsAttributes($string);
//}

It should work now for your version of libxml.

You will need to edit the affected entries, though.

Hello Pat

I'm glad to hear the issue was resolved.

If you were to go with commenting that line of code, you're correct - you would need to do it again when the plugin updates. That is - if that resolved the issue, it would indicate your libxml version is outdated, and if you don't update it, you would need to comment the line of code in our plugin, to resolve it after every update.

However, since reinstalling the plugin fixed the issue, I don't think that's the case on your website.
