Thanks for the additional help!

I decided to press on with a new install, along with copying some of the config files into the new .config/calibre folder. Trial and error takes a while, but found out what works and what didn't, LoL.

Anyway, I cannot find where my "Search and Replace" regex and character S&R's were stored. I had probably 40 custom items in my list.

Any possibility those might still be in my backup somewhere? File name?

Thanks!

[Update]

Well, I found the file, and by good fortune, all my regex's were there. But, during the process of copying that file over, I discovered what was probably causing many of my problems previously:

The backup files somehow got changed to 'root' ownership. So while I was copying the files over as 'root', I did not think to look at the file permissions. Once I changed ownership and group ownership, at least this file was picked up by Calibre just fine!

So, now have all plugins, etc loaded. There are some minor catalog generation stuff I need to tweak to get it back to what I had, but now it is pretty much the way I want it.

Thanks everyone for the tips, pointers, and help!
