Hi Cena,
Thanks for your assistance.
We haven’t made any changes to the site or installed new plugins in some time.
We have tried deactivated all of them to see if this resolved the issue, but no luck
These are the plugins we have installed:
Akismet
Jetpack by WordPress.com
Select Login With Ajax
Select MCE Table Buttons
SB-RSS_feed-plus
Select Simple Share Buttons Adder
Yoast SEO
To us it appears to be a server issue but long conversations with Godaddy have failed to find a resolution.
All help appreciated.
Thanks,
Daniel
