Thread:Project:Support desk/Upgrade 1.22.7 to 1.23.0 --- problem with shared database/reply (2)

What the script says is right :) the parameter you give is "--doshared" which isn't a correct parameter for command "php". You want to give an argument to the script you want to run, so type first the command, then the parameters (in your case no parameters), then the file and after the script file the arguments. Correct call is: php maintenance/update.php --doshared
