I'm glad you included the debug log. It showed you are using Calibre 4.23 and this is a py2 vs py3 issue with regular expression handling.

A recent change to better handle 'tags' in thread titles on XenForo sites works in py3, but not py2.

Here's a stackoverflow question about it.

I've opened an issue and it will be addressed, but I want to give the hseg a chance at it first.

In the meantime, you (Ian.M) could:

1. Continue to use the previous FFF version
2. Switch to Calibre 5 and the latest FFF
3. Reinstate the previous tagstitle handling in your personal.ini. Spoiler below.

Since you said you don't already have a [base_xenforoforum], it should be pretty easy to just put this in your personal.ini.

Spoiler:
