I'm struggling with an online-shop I'm currently developing. It was actually almost finished, when I realized the dev-environment was listed on google. I activated the Windows-Authentification, so no one could order the not-correctly listed products.
It seems like I inserted a new product in one of my 100 tabs that were actually in an older session (when the Login wasn't implemented). Since then, i get an error-message, no matter which page I try to load:
"Value cannot be null.
Parameter name: merchelloContext"
The merchelloContext-Singleton-Instance seems to not be accessable anymore.
Checking the umbraco-log-file revealed the following Error:
2017-08-03 22:32:40,141 [P3868/D4/T28] ERROR Merchello.Web.UmbracoApplicationEventHandler - Initialization of Merchello failed

Then it became scary:
I tried a backup I created 2 weeks ago (application-folder AND database).
Same problem. Same Errormessage. I clean-installed Umbraco & Merchello(incl. FastTrack). The Tshirt-shop worked fine. When I updated the connectionstring to the backuped database, the error appeared again.
It seems like the Cryptographic-Exception somehow destroyed some kind of serverside cookie I'm not able to find. I'm almost at that point where I start again from scratch, but then I would need to re-enter all 268 products (incl. product-variants)... I already tried rebuilding the indexes @Devs->Examine Management (as Rusty suggested in a related problem), but nothing changed. Adding a machine-Key also didn't change anything. I also tried using multiple devices and deleted my cookies multiple times (in different browsers).
Im using Umbraco 7.5.11 with Merchello 2.5.0
I hope you guys can help me safe some time, I'm really desperate.. Thank you in advance!
I just happened to move the shop to another server. The last time (when I created this thread), I just re-entered all products. NOW, after migrating the whole page, i encounter the exactly same error.. Is there still no one with any clue or idea of what to try out?
'merchelloContext is null' after CryptographicException
