Topic on Project:Support desk

I'm trying to upgrade from 1.16 to 1.21.1. I have created a new installation for 1.21.1 and copied my LocalSettings file to it. I'm trying to do the web update (because i don't have command line access). After i type in my UpgradeKey, it goes to a page that shows:

Environmental checks

Basic checks are performed to see if this environment is suitable for MediaWiki installation. You should provide the results of these checks if you need help during installation.

• PHP 5.3.25 is installed.

...and that's it. There is no next button or anywhere else to go. I'm guessing it ran into some kind of error on whatever other environmental checks it's supposed to be doing, although i turned on error reporting for the mw-config/index.php file and all it shows is "Warning: passthru() has been disabled for security reasons in...includes/GlobalFunctions.php on line 2854" which seems unrelated.

Does anyone have any ideas? Does anyone know which files are being used at this step of the upgrade? Maybe i could edit them to bypass whatever it's getting stuck on?

Could you paste the results of phpinfo()?

I was able to solve (or at least avoid) the problem by removing "Welcome" from the $pageSequence array in includes/installer/WebInstaller.php.

For reference, here is my phpinfo:

php version 5.3.25

So, has the problem gone away? How far does it go now?

Yes, the problem is gone. The remaining web installer pages worked fine (updating the database tables etc).

For future reference here is a bug about the passthru problem.
