OK from the includes directory
Minus the password and user names
Your config.ini has a few issues that stand out to me -
[*] the opening "<?php" is missing from your quote. Probably just a copy/paste thing?
[*] dumpdir' => 'teamzr1.com//ubbthreadsubackup', -- There is an extra slash in your directory name.
[*] 'SFS_KEY' => 'sm842', -- The key is too short. But you may have truncated it so as to not publicaly share it.
[*] UPLOADED_AVATAR_PATH, UPLOADED_AVATAR_URL, SQL_LOG_PATH -- Paths are missing.
Minis those few items, the rest looks ok to me upon quick visual inspection of that config.ini file.
Mark also has posted a very good reason for why you might be seeing that additional language option listed. It is definitely not any part of the UBB.threads software, nor has it ever been a file ever included with any release of UBB.threads. My guess is that it was accidentally copped/moved (or on a GUI, dragged) from another location. If it was moved from another location, that may be the cause for some of your random problems. System configurations functioning as default/vanilla, rather than what your other server processes/programs were specifically configured to expect.
EDIT -
Some hosts allow for one single php.ini file to control everything in the home directory and lower. Some hosts allow for separate php.ini files in each directory to control everything within that single directory and all the sub-dirs beneath it -- giving you the option to run different php.ini configurations at different levels.
A misconfigured server can over-zealously populate all the sub-dirs with multiple php.ini files, while others (from within the server's control panel) will automatically create a php.ini and insert one/each in to the directory that you tell it to.
Ultimately, I believe the issue may just be an accidental copy/paste or drag/drop. aka, user error.
I'd love to read how you got it all solved, when things are back up and running as you'd expect them to be. Its no fun to have this happen at all, but you're doing the right thing by asking a lot of questions and providing good feedback, and reading.
