mod_security blocking some component content

[davetest]

Thanks shaun_a, I sort of guessed that, so thanks for the confirmation. My current host is 'thinking' about if they can help, so it could cause me a lot of trouble if I need to move :-(

Wow it would be great to find a solution for the future if some encoding method could be considered for future versions as I may be getting a similar problem on another GS site with the Catalog Plugin.

Have you any thoughts on why my problem code that throws an error in components, seems to save ok if in page contents?
