1. In the browser: the blog’s pages, categories, tags and comments appear all to be in the root (Yet, in the File Manager, they are located in the subdirectory).

2. All the photographs and graphic material have remained in the subdirectory (they appear like this in the browser, and also in the File Manager).

3. The larger photos, that could once be opened upon clicking the (smaller) photos on the blog, are no longer visible, and instead you get a 404 message.

I have to add that I have several backups of the site made prior these changes. So, maybe using one such backup to restore my blog’s original location would be a solution..?
