Internal Server Error upgrading WordPress on IIS7 server

  • Mike Malter


    At the top of my dashboard, I see a link to Please update now. When I click on that link, I see an Upgrade WordPress page. There are two buttons, one to Upgrade automatically and the other to Download 2.8.4. When I click on the upgrade automatically button I get an internal server error.

    The address for the buttons is, and the address of the error is:

    Is there something I have to do to get the upgrade automatically button to work?

    I am on IIS7 and have just recently gotton the blog up and running in a Microsoft environment, I have yet to make it live.

    Thanks for any help.

    I am going to update my own post with my solution in the event there are other IIS7 users out there.

    What you have to do is to goto your IIS manager and then left click on the WordPress website. Then right click and click on Edit Permissions. Click on the Security tab and then click on the edit button.

    Then, click on IIS_USERS and click on the Modify permission. Click on OK. This will not only allow an automatic upgrade, it will also allow you to use your administrative pages to download and install everything that is offered.

    Mostly I am breaking my standards in that I NEVER, EVER allow any permissions other than read, but in this case I am truly hoping that the WordPress codebase is secure enough to prevent problems with these elevated permissions.

    I will be watching this like a hawk. What I may wind up doing is to just turn on the Modify permissions when I need them and then turn them off otherwise.

    Not sure if anyone has any thoughts on this. Anyone?

    thanks for coming back with this resolution
    it will be nice to be able to refer folks to this thread
