Unexpected Website Error - Object reference not set to an instance of an object.

jokerfest

I am getting this error all day every day. Probably about 1 out of ten clicks.

Doesn't matter if i'm going into node details, opening the admin page, clicking the home button.

I hit F5 and the page almost always loads after that.

This is driving me up, over, and off the wall.

Thoughts? Thanks.

I encountered that error before and found it was caused by IIS crashing. Have you already applied Orion Hotfix 6? I see that you're still on NPM 11.5.2.

What version of NPM are you running?

Can you click the SAVE ERROR REPORT LOCALLY button and show us the full error log?

I encountered that error before and found it was caused by IIS crashing. Have you already applied Orion Hotfix 6? I see that you're still on NPM 11.5.2.

jokerfest

No, but I'm in the works to upgrade orion and npm to the newest releases.

I was hoping to know if it was a bug other people had experienced or if it was a performance issue. My server is very taxed until I can update/upgrade.

jokerfest

I will be moving site to a new web services server/license. I will also upgrade to the newest release at that time.
