Noting that no thickes have been closed since 2014, in as much as we like to know what needs to be fixed in our 'stuff, we thought that we would let you know that - under PHP 7.0 on Apache 2.4 / Ubuntu Server 16.04 LTS - that we are unable to edit any previously created entry. When attempting to so do, all that is displayed is:
"Edit Entry
Are you ready to blog? If you're using text styles or including images, remember to 'close' all your 'tags'. Fill out the form below and click 'Preview' to see how your entry will look, or click 'Post' to save your entry."
Nothing else is shown.

The problem was due to my "A" records - as managed by my ISP. Forwards to a dotted quad + folder name, rather than the classic URL. Yikes.
