Hi there,
Can you provide us your ftp access at http://stackideas.com/dashboard/site, it seems there is an issue with your backend where it cannot load after the cache settings in the Global Configuration was disabled.
By the way, your blog menu seems to be working fine now. I suspect your template's cached javascript file was causing the issue.
Let us know, thanks.

Hi Raymond,

I thought you guys had gone home so I re-installed a backup for now and made a copy on ifdsmarketing.com/onetest/ to see what happened when updating again.

Will run the update now.

Managed the first update to 5.0.37 but I see it's still saying there is another update?

I entered my API key and now the update message has gone. I'm going to give the actual site another go - oneifds.com

What cache setting should I be running in the Global Config and are these just for updating?

Hello there,

The new version retrieval is running on a new mechanism and you are required to enter the API key to utilize this service. This is to prevent unauthorized users utilizing up our bandwidth each month.

As for the cache, you don't really need to change anything and it should update just fine.
