OliverA, aaronk, alwaysbusy, thanks.
There seem to be several factors in play. On my personal laptop, that Chrome Server Plugin and others from one of the Banano projects was active. I removed that, and the resulting page reflects the index.html, on port 8888. On port 12612, nothing seems to happen. However, I haven't looked at it in debug mode, yet.
On my office PC, yes - lots of things that could cause this problem.
First, on the office PC, I did the same thing as the Personal Laptop. I removed
Web Server for Chrome
JetBrains IDE Support
Simple Websocket Client
, and Chrome isn't much different. IE seems to be working fine, though.
In debug mode, several candidates for root causes - There is a 404 error in the log, even though it doesn't show up on the web page.
For one thing, the service worker is activated. There's also a missing banano function in there.
The basic problem is that I copied a Banano-generated index and app.js file into the server folders. This is obviously the source of the issue. I'll go ahead and do a cleanup, on the personal laptop, office pc, and home desktop.
Thanks and regards,
