I see only one pasted log. I'm unsure what you mean by "entries".I have pasted the log entries below--not a lot of them, and they do look like the ACP Console entry above.
It's also hard for me to support old versions of ACP, I have to retrieve the old outdated scripts (s) from the repository so I can work with the source code you are running. You do have current support and upgrades (thank you!!).
The error is a result of ACP trying to convert the filter number (13) that was selected as the Dark filter in your ImageSet. Instead, ACP is falling back to the "ClearFilter that is set here:
This is confusing to me. I'm going to need to look myself at your Plan, your MaxIm filter setup. and what filter info is in the images in your plan. Somewhere tings changed and ACP is looking for a filter 13 and now it sees that there are only 12 or fewer filters.
It's Sunday (what am I doing here ha ha ha???) I'll try to call.
[edit] I called and left voicemail. Let me know when we can get together I need to look at this rather than ask you a bunch of questions.
