Hi cubefree.
Thank you for your post.
This is very likely a file permission issue! The plugin is attempting to respond with a list of searched result but has not been given permission to do so hence your issue.
The recommended values for Joomla is, 755 and 0644 for folders and files respectively. For more information on Joomla’s system requirement please see the official link below:

suPHP is a Apache module which is a recommend server-side requirement for those using Joomla. If you are using suPHP or something similar then you are able to use the recommended values, 755 and 0644 for folders and files respectively. If not then try using the less secure way of 777.
Please see:
joomlawebhosting.ca/joomla-15-tips/69-jo...ile-permissions.html for more on this matter. If you are unsure that this is operational then the best thing to do is to ask your hosting provider.
This is not to say that the editor will not work if you are using a different configuration however, you may have to play around with your servers file permissions to get the editor to function correctly, - So this maybe the cause of your troubles.
Take care,
Paul
