Upgrading Drupal

hi.

it seems there is some problem with one of my sites where drupal is corrupting some of the data - it is making "'"s into "’"s as well as mangling other characters. this seems to be happening on a live drupal site during the submitting of new data.

does anybody have any idea why this could be happening?

the strange thing is that it actually looks like it might display ok on the website - but only in some instances.

I recently upgraded to 4.6.2 from 4.6

but when i change theme I'm getting a
warning: call_user_func(xtemplate_templates): First argument is expected to be a valid callback in /home/******/public_html/drupal/modules/system.module on ...... this on the face off it dosent appear to be a serious proble until you start messing with the style sheets then the problems start emerging I was using a blix theme

I initally thought this was a problem with my local installation but have found out not its also a problem on my server

heyas..I tried an upgrade..I have a lot of custom menus on the left and right sides that took hours and hours to create....here is the site with teh 4.4 database:

http://herman.redirectme.net/rocket/

when I did the upgrade...here are the errors:

http://herman.serveftp.com:1028/updatephp.htm

any tips on how to fix this? Redoing all those custom menus would be too time-consuming to be worth the upgrade....

i upgraded a few weeks ago to drupal 4.6.3 and i am no longer able to add users. well, i get sent an email telling me someone has applied for a user account, but when i go to activate it i get this error:

Cannot modify header information - headers already sent by (output started at /home/machine/public_html/blog/includes/common.inc:384) in /home/machine/public_html/blog/includes/common.inc on line 192.

When I attempt to add a user, either as an administrator or as the anonymous user, the email address receives the confirmation email, but the user is not added to the database. The following PHP error is logged:

Help! I have followed the directions to upgrade my old Drupal 4.6.2 site to 4.6.3. I could not simply apply the patch because I do not have shell access to my server, which I believe is necessary to patch Drupal... so instead I downloaded the entire Drupal 4.6.3 and did everything as outlined in the Upgrading section of the Install.txt file. But just in case let me reitterate what I did:

1. Backuped up my database and my entire Drupal directory
2. Logged on as the user with user ID 1, my admin user account.
3. Removed all the old Drupal files then uploaded the new Drupal files into the directory that I run Drupal from.
4. Modified the new configuration file and made sure it has the latest and correct information.
5. Ran update.php by visiting http://www.kamrani.net/update.php (my root domain)...

When I ran update.php it asked me to update from the latest version 2005-04-14, which I selected and it returned no errors. BUT now that I've done that, I try and log into my site and I get a "error 500: Internal Server Error", which states below it, "The server encountered an unexpected condition which prevented it from fulfilling the request." I have tried to remove the entire 4.6.3 directory that I uploaded and put up my 4.6.2 directory and relogin with the same error coming up. Just in case I have flushed my browser's cache to rule out the cache showing up the same information. All node links I press also bring up the error 500 as well. I have reverted back to 4.6.3 with this error continuing.
