Issue After Upgrading from DNN 09.13.9 to 10.1.2 - ArgumentException & TypeLoadException Errors(CachingProvider &ModuleIndexer) Started By Shivam S I recently upgraded my DNN website from version 09.13.9 to 10.1.2. After the upgrade, I started encountering several errors in the logs related to caching and module indexing.

Specifically, the errors indicate an issue with an empty or null CacheKey parameter, causing a System.ArgumentException. Additionally, there are several System.TypeLoadException errors, indicating that types such as D...	1	313	1	10/27/2025 10:07 AM by Shivam S
After attempted upgrade (10.00.01 → 10.01.01), clicking Update in HTML module crashes site and triggers JIT debugging Started By D0rk52 DNN Platform: 10.00.01 (attempted in-place upgrade to 10.01.01) Behavior: No installer errors reported, but editing any HTML/Pro module and clicking “Update” crashes the site. The server then prompts Visual Studio Just-In-Time debugging (VS tries to attach to w3wp). Front-end recovers after app pool recycles. probably attempt again today.	14	616	1	10/3/2025 1:46 PM by D0rk52
Upgrade path from v. 09.13.08 (0) to current version(s) Started By G_Papadopolis Not sure if there are any notes or instructions for upgrades from 9.13.08 to the most currrent version which appears to be 10.01.2 as of today. Should the 10.0.0 upgrade and then 10.0.1 and then 10.0.2 etc be followed or should the upgrade from 9 to 10.01.02 work I understand that backup of the site and database is a prudent part of each upgrade. Thanks	4	291	3	10/15/2025 8:53 AM by G_Papadopolis
