Technical Difficulties

Saturday, 14 April 2018

Readers may have noticed some technical problems with this 'blog over the previous few days. I believe that the problems are resolved.

Recently, browsers have become concerned to warn users when they are dealing with sites that do not support encryption. Simply so as not to worry my visitors, I have tried to support the HTTPS protocol.

But I found that WordPress was still delivering some things with the less secure HTTP protocol, which in turn was provoking the Opera browser to issue warnings. At the WordPress site, I learned that I needed to modify two fields.

Unfortunately, changing these two fields broke my theme — my presentation software — so that fall-back text, rather than the title graphic, was sometimes displayed; but I didn't discover the breakage for a while, because the symptom wasn't always present. Ultimately, I realized that something were amiss. I tracked the problem to inconsistencies in how WordPress determines the protocol of the URI of the 'blog versus that of the directory holding the themes.

I recoded my theme to handle this inconsistency. (In the process of this recoding, my 'blog was made still more dysfunctional over several brief intervals.) My code is now sufficiently robust that it should not break if WordPress is made consistent in these determinations.

HTTPS

Friday, 2 June 2017

This site now supports HTTPS connections. For most visitors, an HTTPS connection will mean no more than that they won't receive a spurious warning from their browsers about the site being insecure. For friends with accounts giving them access to restricted entries, HTTPS will allow them to be less concerned about whence they log into the site.
