I am trying to update from 1.16.1 to 1.21.1 on a hosted site to which I do not have command line access.

I have installed the 1.21.1 files, copied over my images directory, LocalSettings.php that was carefully tested on a local PC with updated extensions, etc. I ran the update on the local PC to uncover the extension issues, etc, and that worked fine.

I have edited my .htaccess files to disable mod_rewrite so that I could navigate to the update script.

I did not overwrite my 1.16.1 files, I made a new directory for the new files and renamed it to w after renaming my "w" to "w1.16.1"

php Error reporting is set to E_ALL I set max_execution_time to 1200 !!!!

When I run :

mydoc_root/w/mw-config/index.php5

I get a totally empty page and the navigation bar says :

mydoc_root/w/mw-config/index.php5?page=ExistingWiki

But there is no sign that anything is happening. No error message, no progress bar, no clock, no hourglass, nada.

If I hit 'Back' I can get a "do you want to restart your installation " screen, but this gets me no further.

Now What?
