Right side boxes will not display AFTER customer login. Error message instead

[MR4TC]

Hi there,

I have just noticed (when logging in with a test user) that the specials box that displays on the right hand side disappears and I receive an error message! It is all good when not logged in??

https://essentialrc.com.au is the site.

v1.50, been running for a couple of years with no issues. No changes to site for more than a year.

Running on MAC OS 10.11.6, happens on Chrome and Safari!

I have attached a screen shot showing after I log in.

If anyone has a suggestion it would be greatly appreciated.

Cheers, Warren

One of your sideboxes is throwing an error after login; see this FAQ article for additional information.
