The sidebar entries ended up as footers, via some Blogger template error in my usage.
It seems fixed, stable, on the PC image. Not accessing the blog by phone, there may still be problems, but for the PC image, things have been accommodated.
But bottom line - the sidebar is gone, with former sidebar content now displayed as edited footer content.
It's been kludged to a stable PC image on the Win-11 laptop this post is typed upon. The hope is that readers are able to access things. devcrabgrass@gmail.com is an email address to use to inform me of viewing problems although a large part of the day has been spent to achieve stability. If emailing, please test the latest version before noting problems. And as likely as not, I will be unable to do more troubleshooting, but getting notice of "okay" or of "botched up" would let me know how effective the kludge has been. Thank you for any attention you can spare.
Sorry about that.
