That's the lot!

I have deactivated the two plugins mentioned in the first few screenshots, but this hasn't fixed it.

Whoops. I should have said just errors...! 99% f these are CSS issues which wont effect code. You always get a lot of these with WP and they are usually harmless. I would suggest that the issues lies with whatever is showing this error:

TypeError: $(…).Jcrop is not a function

This could be caused by a plugin (something tp do with images clearly) - and it IS coded incorrectly for the WP API - or it could be caused because one of the plugins (or your WP theme) is incorrectly loading jQuery libraries and bypassing the WP API and protocols. This is explained in this codex article:

http://codex.simple-press.com/.....-conflict/

so you could look at the source code being generated to see if either of these libraries is NOT being loaded from the WP 'wp-includes' folder.

Thank you Yellow Swordfish!

I have disabled all slider plugins / thumbnail plugins, except for the one I'm using on my home page - and Simple:Press works. Woo hoo! Will follow up the advice in the article you suggested later today. In the meantime, I now have a work-around.

Phew!

namaste!

Clare

excellent news.

Now if we can narrow down exactly which plugin and what the issue is then  we should - hopefully - be able to come up with a strategy to resolve it.
