Upgrading Drupal

I have just updated my site from Drupal 6:10 to 6:13 but the update.php file loads a completely blank screen. No error messages, nothing.

There were white-screen-of-death problems on the site before the update that I hadn't solved and I'm wondering if this could have something to do with it?

I urgently need to get this site up and running again but have no idea what to do next.
I've just tried to reinstall Drupal 6:10 and it will be done in 5 minutes but I have a feeling that it's not going to work.

I am getting the following error message since I upgraded:

Fatal error: Only variables can be passed by reference in /home/urbanmi/public_html/LIFEWITHSLEEPAPNEA.COM/sites/all/modules/admin_menu/admin_menu.inc on line 521

This error message happend when I try to go into the Modules section of the Admin area. Can anyone please help.

I just figured out how to post a new topic rather than replying to an existing one. I hope someone can help me with the following problem.

I just set up Drupal 6.12 about six weeks ago.
We had to modify the php.ini to get it to work, but we got it going.
I have not done much with the Drupal web site yet.
(We have a full web site that is written entirely in HTML, and I have been procrastinating about migrating the web site over to Drupal. I'm excited about it, I just know it will be a lot of work.)

Anyway I've been reading the Drupal Users Handbook and was excited about FINALLY getting started creating some nodes and doing some things today. However, when I logged in, I saw there is a new version with "required security updates" in RED Letters. I also had read that we are not TRULY "required" to update anything until it goes to a whole new version such as Drupal 7.0 instead of Drupal 6.x. However, I figured, why not update it, since the only work I've done so far is configuring the php.ini and other files to get it to work with my internet service provider. I figured I could just save the files that were updated and save them into the new Drupal 6.13 directory.

So, from Drupal.org, I downloaded and unzipped the Drupal 6.13 folder to my hard drive.

How to create a block which lists the teaser title of the recently posted pages on my web site front page

The calendar views have disappeared since upgrading modules (event, date, views, view_bonus, calendar, date). The page where the calendar displays shows the heading of the calendar but no days or week (the whole grid of the calendar is missing).

So it has the calendar month / header with the "<

Hello:

First, I'll admit I'm new to the whole Drupal thing. I'm really only responsible for installing it and keeping it running; others do the actual content building.

I'm running into what seems to be a common problem, in that I can't upgrade from 6.10 to 6.13. I follow the directions in the UPGRADE.txt file, put the new files in place, put my sites and modules folders back in with the new stuff and then run upgrade.php.

The upgrade SEEMS to run with no errors, but the blue status bar (I just noticed) says...rmmm...something like "Running update 0 of 0".
