I have encountered an error with one of my sites involving the wordpress core.
When i install any version higher than 3.6.0 i encounter the glitches shown in this video:
I have never seen anything like this in the 2-ish years i have been using wordpress.
This particular site is a bit of a unique case, though, for other reasons.
The client this site is for has their own webserver. it is a windows server running IIS 11.
The site is self-hosted on this server (they do not use a web host like godaddy or hostgator), This was something they had established long before they hired me.
They also are a small enough company that they do not have an IT department to deal with server problems, updates, etc.
Has anyone encountered a problem like this?
any ideas on how to fix it (other than not updating the wordpress core)?
the site in question is currently located at http://americanindustrialinc.com/wp
