Thanks for your reply.
I should have clarified—I’m quite a beginner at all of this. I was taking over where someone left off (who disappeared suddenly) and am hardly qualified to be doing any back-end stuff.
I essentially have no server information, simply the WP login info which is where I have been doing the bulk of the work. I don’t know anything about internal server errors or how I go about figuring out who the hosting provider is, let alone how to contact them.
Simply put, I’m panicking and very unsure of what to do. Appreciate any advice or solutions, the simpler the better.
