I won’t be offline now.
New theme is installed. It’s clearer but parts are positively witless! For example, links are simply shown as bold, no underline or any other indication that they are active links. This means that people will either assume they are just bold text, and ignore them, or be clicking futilely on bold text in the hope it’s a link.
I’ve fixed the problem, and links from today will be the normal blue, but that will only apply to new posts, going back over way more than 1,800 posts and four and a half years to fix links that have been screwed up is out of the question.
