Hi Steve, thanks for your reply.
Like I said I’m a novice, I don’t know where to find the server, what’s the error log?
How do I enable wp_debug and debug_log, where or how do I do that?
And how do I disable the plugins, if I cannot get onto my wp-admin dashboard to manage the website?
I was doing some ‘spring cleaning’ on my file manager to recover some space, is it possible I deleted something critical that hasn’t been utilised in the past three years, or is it a simpler issue?
