i've got bLOGengine.net 18.104.22.168 running using sql server - works great, however, i recently changed an <img> in site.master and it then kicked out an internal server error (500). No problem, i thought, i'll just restart the site - no go.
I've also resetiis - no go. If I replace the original site.master, it works fine.
Incidentally the new site.master with the new <img> tag works fine on my local machine, naturally.
Upon investigating this a bit further i found this error:
This configuration section cannot be used at this path. This happens when the section is locked at a parent level. Locking is either by default (overrideModeDefault="Deny"), or set explicitly by a location tag with overrideMode="Deny"
or the legacy allowOverride="false".
Again, no changes other than adding an <img> tag to site.master have been made, especially no config changes.
