When I write a post or a page and want to use the 'add an image' button, the gallery window does not pop up anymore, nothing happens in fact. It used to work fine in the past.
I can upload files by going into 'media' and by using the 'browser uploader' but that way is quite laborious as I need to attach the files to the relevant post and pages and need to copy the images path and paste them into the page or post!
Can anyone give me any guidance on how to get this sorted? I am thinking to re-upload the wp-admin folder, would that be wise?
