Comment (by ken01102018):

 Replying to [comment:19 derekpadula]:Derek, I finally discovered the cause
 of my problem, quite by accident.  After numerous manual updates, partial
 backups that did not cure the problem, I was about to give up.  Then when
 looking at my media files, I noted that the most recent image uploads had
 the file type avif.  Upon looking into this, I found that Apple's Safari
 does not support this Google Chrome promoted image file type. I had
 apparently decided to switch to this image type for some reason around the
 same time as WP updated to 6.5.5.  So it was just a coincidence that my
 problem happened after that update.  The avif images are said to be
 sharper and have better color rendition than webp, so maybe that is why I
 decided to try that file type output and I had forgotten about that change
 and even if I had remembered, I would probably not have made the
 connection just based upon the file type.  The fact that all only the
 images uploaded after WP 6.5.5 were avif made me make that connection.
 I've deleted all of those image formats and reverted to webp format images
 and all is well.  Lots of background work for what turned out to be a
 simple problem.  So I falsely blamed WP, when it was a browser issue.  I
 know you suggested trying different browsers, but I've had significant
 security issues with other browsers, especially Chrome, in the past, so I
 don't like to install any other browsers on my Mac machines.  Sorry for
 all the hassle, but thanks again for your help.
 > I updated to 6.6 in the WP admin, and I am able to insert images, so the
 original issue is no longer present.
 >
 > The issue was resolved when I manually uploaded the files from 6.5.4 and
 then 6.5.5 via FTP, and now seems to be okay when updating to 6.6 via the
 admin. I don't know why that is. The best I can figure is that it was a
 file permissions issue, or a web quota issue on my Nginx and Virtualmin
 VPS, which may have been resolved by changing the quota on my user and
 group from "1GB" to "Unlimited." In any case, I'm going to close this
 ticket as resolved (works for me).

 > Ken, you may want to ask one of your sons for help. Since it's a website
 and server, they can do it from anywhere. Give them your log-in info and
 it should only take them 10 minutes if they follow the steps I outlined
 above for reverting to 6.5.4.
 >
 > Then, just ''don't update'' the core WordPress files. It's that simple.
 >
 > * You can still update plugins or add and remove them.
 >
 > While it's bad advice in general to not update because of security
 concerns, in your case it won't matter much. You're not selling anything,
 aren't holding user info, and are only sharing photographs, so you don't
 have any major vulnerabilities. Instead, approach it like a large business
 where they lock themselves into a particular stack of software for a few
 years, and they only think about updates again at the end of those few
 years. Then you can focus on sharing your pictures and enjoying your site.

 > Have a good one.
