I've just been looking at my logfiles and I find that there many warnings/errors which appear to be related to PHP:

Can anyone suggest what might be causing theses and how to eliminate any problems?

Both of these are covered in this post along with many other things that you should take care of before upgrading to recent versions:

Preclear plugin requires an update to silence these errors.  But, the only reason you're seeing them is because in the tips & tweaks plugin you've enabled show PHP warnings.

Strange - I already have Preclear 2018.04.27 installed.  Is there another one?

I'm not aware of another browser window/tab being open, but would this also occur if the server spontaneously rebooted itself while a single browser tab is open.

May need a reboot.  If that doesn't clear it up, then the author still has more work to do to silence them

yes.  Until you refresh the browser
