Upgrading Drupal

Is Drupal somehow incompatible with PHP 5.3? I get loads of error messages after upgrading to PHP 5.3.

Only option is to downgrade it?

I installed a new D6 then tried to migrate a db from D5 to my D6 install. I uploaded the sql file without error and saw that the # of tables incremented then I ran update.php without error but if I check the content of the site I see nothing.

Is there any solution for this?

thanks,

Hi,

I just updated my site and all seemed to go well,
I noticed a few errors after updating the date module

warning: include_once(sites/all/modules/date/theme/theme.inc) [function.include-once]: failed to open stream: No such file or directory in /home/xxx/public_html/main/includes/theme.inc on line 286.

warning: include_once() [function.include]: Failed opening 'sites/all/modules/date/theme/theme.inc' for inclusion (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/xxx/public_html/main/includes/theme.inc on line 286.

Amazingly, after learning Drupal and reading this and other websites/guides for weeks, I cannot find information on "How to update a module?"
Where is it in Drupal's documentation?

Happens every time I try to run updates; some of the modules and themes work, some of them don't.

This time around, it's views 6.26->6.27 and webform 6.27->6.28->6.29. I followed directions and ran update.php and CCK and the Zen theme updated just fine, but view and webform didn't. Actually, webform has been giving me trouble for a couple of weeks, first when I tried to update from 6.27 to 6.28, and then again when I tried to update to 6.29.

Is it worth updating again, this time choosing the specific version(s) instead of letting Drupal find them?

After many hours I know that I have this problem:

Fatal error: Call to undefined function memory_put() in /themes/engines/phptemplate/phptemplate.engine on line 12

Drupal 6.14

Code fresh; sites/all/modules renamed.. but anyway its the themes engine...

And I did know that there would be days like this!

Any help is very much appreciated.
