SQL Exception in Active Forums – Invalid Length Parameter in LEFT or SUBSTRING Function Started By D0rk52 Hi all, We’re running into a recurring SQL exception within the Active Forums module on DNN 10. Here's the core error message from the logs: Invalid length parameter passed to the LEFT or SUBSTRING function. For now, we've documented it and are investigating further. If anyone has patched this or can point to an updated stored procedure or module release that addresses this, we’d appreciate the help! Thanks, —Joseph https://azmanagedit.com	1	267	0	7/6/2025 7:19 PM by D0rk52
Using Store Modules to Display Service Offerings – A Creative Approach? Started By D0rk52 Hello folks, This might sound a bit unconventional, but in the past, I’ve used store modules to list and display service offerings—almost like a catalog. It’s a great way to avoid creating individual pages for every service. Has anyone else tried something similar in DNN I’m currently exploring modules or methods that let me present managed IT services in a clean, searchable layout—without the overhead of building a page for each one. Would love to hear what others are doing!	9	480	0	6/20/2025 3:15 AM by D0rk52

How to Add Same 2sxc Blog Module to Another Page With Separate Content Started By D0rk52 Hi everyone, I'm working with DNN 10 and 2sxc v19.03.05, and I’ve run into a challenge while trying to reuse the 2sxc Blog module across multiple pages. Goal: I want to add the same Blog App (2sxc-based) to a new page but have it display completely separate blog posts from the original (not shared content). For example: /services uses the Blog module to show service-related posts. /blog should show general or news-related posts — different content entirely. Prob...		301	0	7/1/2025 2:23 PM by D0rk52

Structure Content DB Schema Started By John Wolf Do all the DNN structured content tools use the same database schema I'm thinking about Open Content, 2sxc, Live Visualizer and FnL. What I mean is, is a standardized DB schema part of this thing called 'structure content,' or does each vendor do it's own thing If it's consistent, is it documented somewhere We use a few of these tools and sometimes would like to use standard SQL on the tables. The manner in which our data is stored is a mystery. Thank you. John	4	348	2	6/27/2025 9:43 AM by John Wolf

Forum Group Names Showing Twice – Help with Cleanup Started By D0rk52 Hi folks, I'm using the DNN Community Forums module and currently setting up the structure for my MSP site: 👉 https://azmanagedit.com/Community-Forum However, I noticed that my forum groups (like General IT Support and Web & Hosting Management) are showing up twice — each with different forums underneath. I’m assuming this is due to duplicate group names being created instead of all forums being placed under a single group. What’s the best way to clean this up and merge the forums under...	6	289	0	6/20/2025 3:12 PM by D0rk52
