Sorry to hear you are having issues with your editor on your hosting account. With the instance on the server not showing the 'Select' and 'Select Thumbnail' options and your local host showing them, it appears it may be some sort of configuration difference.

If you can glance at both configurations and let us know what is not the same between your account and the localhost, we can advise on whether or not it is something we can change.

It is not a major configuration issue otherwise we would see other programs having issues. If you are not able to discern the differences, you may want to check with kcfinder or ckeditor support. They may know exactly what setting needs to be changed.

If there are any error messages, then we are happy to check within the server to see what we need to change as well. Simply respond with the specific message so we can assist.

Kindest Regards,
Scott M
