Thread:Project:Support desk/Fatal error after upgrading to 1.19.2/reply (6)

First of all: It's unlikely that running the installer solves your CSS problem. I would restore LocalSettings.php; most likely deleting it will cause more trouble than it solves. ;-)

Second: Have you run update.php successfully now? You should have done that at least once.

Now to your latest problem: If the CSS is missing you likely have an issue with accessing the file load.php, which is used to display the CSS styles.

View your wikis sourcecode with the webbrowser. In the top part of the code you will have some links pointing to load.php. One of them is responsible to load the skin. Copy this link and try to open it with your browser.

You should see (maybe compressed) CSS code. Do you?
