Ok I'm still having the same issue, but I'm 95% sure it's something on my end.
I've tried different computers, different browsers, removing the one italize html tag I have in it, saving it to notepad then copy pasting it over, made an attempt at adding to it bit by bit but still couldn't use the save button without the error, turning off the extension, and probably a few other things I'm forgetting and will eventually repeat today.
However, I did shorten the Article Title and got a new error that I haven't seen before.
Microsoft OLE DB Provider for SQL Server error '80040e2f'
The UPDATE statement conflicted with the CHECK constraint "CK Articles - Row Validity". The conflict occurred in database "MyAdventureGame", table "dbo.Articles".
C:\WEBSITES\CHOOSEYOURSTORY\CHOOSEYOURSTORY.COM\HELP\ARTICLES\../../Includes/Components/Article.vbs, line 149
And now the article shows up as if it had been saved, even though I didn't save and only submit.
