Upgrading Drupal

When trying to run the update.php just after getting HEAD from CVS, I get the following error:
Parse error: syntax error, unexpected T_SL in /home/dieinte1/public_html/devel/drupal/update.php on line 788

I upgraded my website from 4.7 to 5.2 beta

1. I did the backup
2. Logged in as an admin
3. Removed all the old Drupal files and installed Drupal 5.2 beta.
4. Modified the new configuration file for database.
5. Run update.php and it went well.

However I get the following error while accessing any page:

Fatal error: Cannot use string offset as an array in /home/....I removed.../includes/theme.inc on line 532

I just upgraded my site to 4.7.4 from 4.6.X everything went fairly smoothly after upgrading modules and themes. I have one error I cannot figure out. When I try to enable my upload module I get these errors

* user warning: Table 'airrace_airrace.file_revisions' doesn't exist query: SELECT * FROM files f INNER JOIN file_revisions r ON f.fid = r.fid WHERE r.vid = 2 ORDER BY f.fid in /home/airrace/public_html/includes/database.mysql.inc on line 121.

* user warning: Table 'airrace_airrace.file_revisions' doesn't exist query: SELECT * FROM files f INNER JOIN file_revisions r ON f.fid = r.fid WHERE r.vid = 126 ORDER BY f.fid in /home/airrace/public_html/includes/database.mysql.inc on line 121.

I've disabled the File Manager and File Request hoping that it might be related but to no avail. Anyone have any ideas as to what might be causing this? I re-uploaded the upload module in case it had been corrupted when being uploaded the first time, but still get the error. The ability to upload a file with a node is fairly important and it would be great to get it working again. The site is www.airraceclassic.org.

Hi all,

The documentation says to run update.php after a module upgrade but the update.php page warns that the script should not be run more than once. Which one is correct?

1) If it shouldn't be run more than once it is a security risk leaving the file in place as anyone could mess up your site by running the script.

I had been running a pre-release of 4.7.4 (it was identified as 4.7.x-dev) for a few weeks.

When I tried to upgrade to 4.7.4 yesterday, I started seeing the following message every time I tried to access any page (while logged in as the super-administrator, ID = 1, user):

"You are not authorized to access this page."

I then did a completely fresh install; I created a brand new MySQL schema, using a name different than the one I had been using. I installed drupal 4.7.4 into a new directory on my server (Apache 2.2).

Hello guys,

Really I'm gonna insane here..really I can't find a clue to this problem..

My hosting company finds some problems with my drupal version, and from time to time it closes my site for while which really affects my traffic..

So now I need to upgrade my drupal to a newer version, as there are alot of security problems in my site..and here comes the problem, that I dunnu my drupal version..really that' a very big problem..
