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/codex/faq/troubleshooting/what-is-this-jquery-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.
