Hey Dennis

Thank you for your purchase, and for your kind words.

That sounds pretty strange. 

Please provide me a temporary WP-admin login for your site where this happens, so we could log in and take a look ‘from the inside’ as that’s the most efficient way to see and resolve the issue. We do not interfere with any data or anything else except for the plugin (in case that’s a production version of the site), and of course we do not provide login data to third party. You can write credentials here just check Private Reply so nobody can see them except us.

Hi again Dennis

That worked, thanks.

When you hit ENTER in a multi-line cell, the plugin adds a break tag <br />, and for some reason that doesn't work.

Please tell me if we have your permission to debug the issue on your website? We'd simply pass some code into wpdatatables.php using the Plugin Editor, so we could see the actual error response, and see why it's not allowing tags.

Hey Dennis

We just checked the stack trace again, and saw that you need to install this extension on your server. It depends on of your operating system, here are some examples:

sudo apt-get install php-mbstring  # Debian, Ubuntu
sudo yum install php-mbstring  # RedHat, Fedora, CentOS

If you don't know how, or don't have access, please reach out to your hosting provider, and they should be able to install it.
