webcontrol_html seems to have quit working after update

[bamoore01]

I am running 2 RPi4's with motion installed on Bookworm. Both Pi's were working well until I upgraded the OS. The main problem I am having is that the webcontrol_html setting in motion.conf doesn't work anymore. I use the webcontrol page to display both cameras on the same display when I load the it on my phone or computer

On Pi#1, I did a new complete install from scratch 5 days ago. Everything seemed to work OK except that I could not access the html page on that Pi anymore when it is declared in the motion.conf file. I used the same .conf files with no mods for the new install and the instructions under the V5.0 part of the motion web page.

Since the web page was not a top of the line issue for me I went ahead with upgrading the second Pi. First I upgraded with upgrade/update to see if that made any difference. Not only did the webpage access disappear but motion detection also stopped working. I finally gave up chasing the cause and did a new install the same as above. After the install, I got motion detection back but the webpage access did not work. Again, same configuration with the .conf files.

In my motion.conf file I have

webcontrol_port 8085
webcontrol_localhost off
webcontrol_parms 2
webcontrol_interface user
webcontrol_html /home/pi/Programs/motion.html

The way I have been accessing the webpage for this config is;
http://192.168.1.25:8085

It worked before the upgrades but now I get;
Bad Request
The server did not understand your request.

I'm not sure what to try at this point. Any help is appreciated.

Do you have a log showing the messages when you try to open the page? (At the debug level)

I figured out the problem. The older version of motionplus I was running required a full path name for the motion.html file specified in the webcontrol_html entry in the .conf file. The newer version of motion has a new directory in the /usr/local/var/lib/motion called webcontrol. The .conf file now requires only that the file name be specified and that file resides in the webcontrol directory. At least, that is the only way I could get it to work. Also, the configuration documentation on the motion web page still states that full path is required.

Got it. Yea, I put it so that the web control would not provide any page/file outside of the webcontrol subdirectory as a security measure. Only the git version of the documentation mentions it.
