XF 1.2 Undefined Index

[iamjudd]

For some reason I get this error every time a user registers on my forum.
Undefined Index
library/XenForo/Application.php:1101

No user has said they had any issue registering though. Is this something I should be concerned with? Easy to fix?

Thanks in advance

Which add-ons do you have installed?

The first step is to disable them all and test again then re-enable them one at a time until the error reappears.

just from saying that I was able to figure it out
thanks!
