Upgrading Drupal

Hi,

I noticed that the function valid_input_data() disappeared when moving from 4.5.5 to 4.5.6. I was using this in a module I have written myself. The only solution I have found so far was to remove these calls. As I do not see anything on this on the support pages, what do I have to think of when I remove these validation calls? Do I have to add the validation somewhere else?

Receiving error when I try to submit a new post entry after upgrading from 4.6.3 to 4.6.4:

warning: fread(): SSL: fatal protocol error in /home/PATH/TO/DRUPAL/includes/common.inc on line 314.

Also getting header error, probably caused by above error.

warning: Cannot modify header information - headers already sent by (output started at /home/PATH/TO/DRUPAL/includes/common.inc:384) in /home/bplotter/public_html/drupal/includes/common.inc on line 192.

Since I upgraded to drupal 4.6.4 yesterday, the "previous/next page" and page number links (1,2,3,...) have stopped working, I keep on seeing the front page.

So

http://hostname/drupal/

and

http://hostname/drupal/?q=node&from=10

result both in the front page being displayed. Searching for posts still works fine and the node table in the database seems to be just fine too. I am using a postgres database though.

I'm seeing a weird error since I upgraded our production site to 4.5.6 yesterday.

When browsing Forum topics using the "next topic" and "previous topic" links, after advancing a few times through the forum, I'll get an error:

Fatal error: Cannot create references to/from string offsets nor overloaded objects in /srv/www/lliurex/http/drupal-4.5.6/modules/filter.module on line 1023

Is this a known bug I should file, or did I do something wrong when upgrading? Any help is greatly appreciated.

Hey all-

So i started the process of upgrading, but before I could do that, i needed to create a test site. Well, here's the problem:

I followed all the directions at http://drupal.org/upgrade/copying-your-site-via-GUI but now my test site is missing all the design elements from the original. What file did I fail to install?

Fatal error: Cannot redeclare block_help() (previously declared in /home/wizards/modules/block.module:12) in /home/wizards/modules/modules/block.module on line 12

Anyone else getting this message?
