I tried running that, but anytime I go to my browser and type in "wiki.ecovativedesign.com/maintenance/update.php" It says I don't have access and I am forbidden to view the document. But I'm the webmaster! I even tried copying "update.php" into the main directory. Then it gives me access to the document, but says there is a server error. Any ideas?
If you don't know how to run it from the command line, like Jasper suggests, you can do it in your browser by navigating to /mw-config/ and following the instructions there. So, in your case you would type "wiki.ecovativedesign.com/mw-config/" into your address bar. Let me know if you need more help with this.
