When I try to insert a picture, insert media or paste word etc I get a message popping up telling me the relevant tiny_mce file is missing e.g.
The web page at http://www..com/helpspot/js/tiny_mce_338/themes/advanced/image.htm might be temporarily down or it may have moved permanently to a new web address.
More information on this error
Below is the original error message
Error 324 (net::ERR_EMPTY_RESPONSE): Unknown error.
Yet I can clearly see on the server that the file does exist (and the rest of Helpspot works fine)
Helpspot v2.7.2 installed as fresh installation, via extracting zip to local drive, FTPing to server using binary upload and then running Installer.php
Note the issue also existed with v2.6.3
