Not one to answer questions, but definitely one that will be asking plenty of them over the coming weeks and months.
While I'm not a total newbie in the world of WP anymore, I could probably give you nightmares with some of the dabbling 'under the hood' done over the past 4 years.
The end result, and reason why I'm installing a cot in the corner here is I have started cleaning up the mess I've created. And when I see I'm in over my head (too often), I pay for help and fixes. One at a time. Slowly. And learn in the process so I can actually become somewhat competent at it.
So, I will be asking questions fairly regularly, and also posting for jobs as there ARE major fixes to be done.
