Here's what's happening: without making any changes to my setup, today my message board started throwing this error on every page:

It just throws it on the message board pages. I use the Sample Application and all of my own pages (which require the membership system) work fine, But here's the weird part. When I first go to my site, the Latest Discussions all show up as unread (picture 1.) If I refresh the page, suddenly they show up as unread (picture 2.)

What's going on?

No, did you upgraded yet to the latest version?

God knows I've tried. I've uploaded the 3.2.4 Sample Application up to a separate web server to see if it runs well before I try to install it on my main site, but every time I try to run it, it throws an error so I've given up on it for the time being.

Now the error is:

Could not find a part of the path 'h:\root\home\***\install\mssql\upgrade\identity\upgrade.sql'.

This should be:

h:\root\home\***\forum\install\mssql\upgrade\identity\upgrade.sql

Okay, I think we're making progress here! 😁

The stand-alone 3.2.4 seems to be showing up fine now. I just seem to have two issues (so far):

1: You can log in ... it will not allow you to log out.

2: On my forum menu, none of the drop down menus seem to be working.

And may I say also, thank you for your time and effort in getting to the bottom of things here. I know I seem like a PITA sometimes trying to get this to work, but your help and recommendations are very much appreciated.

Yes, and I can see the issue now. The error message states "Loading failed for the with source “http://mfoxweb-002-site3.ctempurl.com/forum/Scripts/forumExtensions.js?v=3”. But looking at the files, the only file is forumExtensions.min.js

Also, are you still using Stored Procedures in the database? I've noticed that almost all of my stored procedures are gone, but the board still works!

To resolve this ether compile on release mode or rename the file.

Correct yaf doesn't use sp anymore.  With orm everything is generated via code. With this solution it works with sql databases such as sqlite.

Do you mean the top logout button inside the sample application, or the logout button from the yaf menu?
