Our Community site (on 10.x) has started throwing error on page

Here is some more detail.  I looked back earlier in the day and just before these errors (referrer changes, but same object reference not set..), it threw this.

REquest: GET /api.ashx/v2/notifications.json?IsRead=false&PageSize=1&PageIndex=0&_Filters_84e4c0a7-3a17-4dfe-b8a0-d7038aa04a84=Exclude&_=1585157564197

Do you have any custom REST endpoints?

Not to my knowledge. It is pretty vanilla.  Where would I find that?

It could be a part of a custom plugin, were any new custom plugins added or update since this started occurring?

No.. system has not been touched in many many months. Also, would the plugin have to relate to the notifications..

I would like to get this to support, but the createcase pages sales my email (on my signed in profile) cannot be found.

I think issue is related to the first error An item with the same key has already been added.

Grant Pankonien should be able to assist you in getting your support case opened.  

Thanks Brian!

Grant Pankonien Please advise how I can get a ticket open. I had trouble from createcase page.

Hey Todd Brotzman! You can see the buttons on the home page I take it since you said you can get to the create case page, is that correct? See your response above actually. Do you actually get to this page: https://community.telligent.com/p/createcase? I'll have the team verify emails match up in our support system and what is in your community profile.

Based on this error, if you are on any version earlier than 10.1.3, then this was was fixed in that service release and the solution is going to be needing to upgrade to the latest service pack which is going to be a version of 10.3.

Yes, but it says email not on conact.. my contact record shows my correct org domain. I cannot get to support portal to update anything .. it always takes me to community.
