I have also moved the site to a new server. The html editor window dosplays fine and tex/style updates work.
However, when you go to insert an image or file, then 'browse server', the file manager window opens, but no thumbnails are displayed, nor subfoldrs that have previously been created.
When you click the 'browse for file', select a file, then 'upload', nothing appears to happen and the winsow remains blank. If you try to upload the file again, you get a message to say the file already exists - even though you can't see anyting anywhere!
I have uploaded all the webassist files, the database tables and everything else I can think of - but haven't changed any odf the web assist files, thinking 'it worked before...'
many thanks, as always
