OK, now we are getting somewhere.
Let me look into this.

Try running SIP with:

Code:

python3 sip.py

[dan]

So far I don't see a problem with the python code.

Could you try renaming the SIP/data/programData.json file to a temporary name like programData.json-hold
Then see if you can access the programs tab.
If not, rename SIP/data/sd.json to a temporary name. and try accessing the programs tab.

[dan]

You may be able to open the program editing page for the first program with:

http://192.168.254.145:8081/mp?pid=0

Let me know of that works.

I ran it with python3 with no luck. I tried the http://192.168.254.145:8081/mp?pid=0 with no luck. Trying the renaming now.

No joy with the latest suggestions.  I'm really at a loss now.

This is indeed puzzling. However I am determined to get to the bottom of this and fix any problem that may be causing it.

Just to be sure of what we know so far:
1. You are getting a "list index out of range" error when you try to open the Programs page.

2. SIP 4 is designed to run under both Python2 and Python3. In Python3 the "range" statement has changed but you are getting the same error under Python3 so that is not a factor. ("$for s in range(8):")

3. Trying to open "http://192.168.254.145:8081/mp?pid=0" also fails. This is trying to open a different page but with some similar code.

Question: do you get the same error message when you try the above?

Question: Can you open the "Stations" page and the "Run once" pages? They also have similar code to what is causing the error. If not, are you getting the same error?

4. Renaming the programData.json file and the "sd.json" files in the SIP data directory does not eliminate the problem. This means that there is not a setting that SIP is not handling properly.

5. you are running a fresh copy of SIP so there is not a problem from the update process.

6. You cleared the browser cache and tried a different browser so there is not a problem from some old code being used by the browser.

Question: Do you have any plugins installed?

I appreciate you patience and help in trying to diagnose the problem.

Hi Dan. Really appreciate your help.

1. Yes.
2. Yes
3. Yes
I do get the same error message when trying both versions of the Programs page.
I can open and use the Run Once and Stations pages.
4. Yes
5. Yes
6. Yes
Looks like I have the mobile app enabled and signaling apps and system updates.

Thanks again for your help!

I should ask what hardware you are running on.

what version of the OS are you running?

Code:

lsb_release -a

or

Code:

cat /etc/*-release

Have you upgraded the OS lately?

Code:

sudo apt update
sudo apt full-upgrade

[tvwebguy]

I'm running Buster. I did update the system, but, I'll do it again just to be sure.
