Support » Localhost Installs » [IIS 6] wp-admin/install.php gives 500

  • Resolved Kiliboraba


    Really struggling getting a 2nd wordpress install on my home server.

    I have one installation set up and working as the Default Web Site. I created a second site for the new blog and meticulously copied the permissions from the old to the new.

    Quick test of – it works!

    Next, using root, I created a new MySQL database for my wordpress user.

    I logged in to myPhpAdmin with my wordpress user and verified I could see and manage the new database.

    Next, I updated my wp-config.php with new info at

    Finally, I tested that php worked by dumping phpInfo() at

    So – I’m thinking things are going to work. I was wrong.

    Navigating to does nothing. Looking at the IIS logs I see:

    2011-11-16 01:39:57 W3SVC654224070 GET /blog/wp-admin/install.php – 80 – Mozilla/5.0+(Windows+NT+6.1;+WOW64;+rv:8.0)+Gecko/20100101+Firefox/8.0 500 0 0

    The last three numbers indicate a crash somewhere. Hmmm.

    Anyone have experience debugging these kinds of problems? If I had to guess IIS is up to no good, but I’d rather not move to Apache because I’m hosting other stuff too.

    Thanks in advance,

    After another day of working on this, I found that php was crashing. I figured this out when I was examining the php.ini file for more clues and discovered it has a log file.

    Looking at the log file I found wp-load.php was failing to open and the whole process would come crashing down.

    Setting the permissions on the “Web Sharing” tab of the properties for my blog’s containing folder seemed to do the trick. I did this through file explorer (rather than the IIS management utility). It looks like the folder had the correct permissions but individual files did not.
