Weird error messages on each page

[sayitlikeitis]

Hi there,

It's been a while since I looked at my site, and was surprised to see these errors.  I've no idea how long its been this way.  I have v1.0.5 installed.  Any advice would be appreciated.  The errors are displayed before the web pages display on each screen.  Everything seems to work okay, in so far as I can tell; its just that the errros kind of ruin the look of every page.

Thanks.

Can you give us a link to your site?

I had these errors on my site at the start, turns out they were caused by some javascript I'd left in the template files

Did you try clearing your cache?

That worked.  Thank you.  I guess that's something we need to do routinely.

hi,
I have the same errors - where do I clear the cache?

Goto Site Admin -> Global settings

Hi,
Thanks,
Why does that happen? I changed the code in class.contentoperations.inc.php to

$usecache = false;
