Waiting for a working 1.1.5 version of the plugin, here's another issue. Same scenario of my previous post, WP and PHP updated to new releases (but the same is with with previous versions...
Admin page options-permalink.php : Default setting is OK, any other setting causes a 500.0 error on this page! More strange, if you reload the page many times, SOMETIMES the page loads correctly.
I tried a clean installation on a test Windows Server using Web Platform Installer and MySQL: no permalink issue. I then installed SQL Server 2012 Express and DB Abstraction plugin, then reconfigured WP site to use both: 500.0 error choosing permalinks other than default!
I don't know where this issue comes from, but it definitely seems to be related to a SQL Server-based WP installation.
Tried different versions of the plug-in: 1.1.4, 1.1.3, 1.1.2, all the same.
I found another user ("ravetroll") experiencing the same issue in this thread so it's not just me.
Someone has any ideas? The rest of WP wite seems to work fine, but the same crash occurs on the whole site with a theme I recently bought that requires permalinks and my client is not happy...
