contacts in database

Contact Form 7 does not do this but the Contact Form DB plugin extension does if you want this.

I use Flamingo, as suggested by the plugin author

does anyone know how to customise colours in Contact Form 7 for the ‘send’ bar?

Probably via your theme theme’s CSS. Try using Firefox with the Firebug add-on for this kind of CSS troubleshooting. Or use whatever developer tool is available in your web browser.

@esmi – I decided not to respond to the post by AllyintheUK as it is IMH0 clearly widely offtopic.

While I do occassionly suggest people start their own thread and not hijack others posts, I generally just ignore offtopic posts.

Interested to hear what you think about this issue in this case.
