Is Drupal 6 compatible with php5.3? We have just upgrade our server and now Our drupal 6 sites are not working properly because now the php version has been changed from 5.2 to 5.3.

is there any guide or suggestion about this? how to run a drupal6 with PHP5.3?

Thanks in advance.

Downgrading the php version from 5.3 to 5.2 solves the php problem and apparently the javascript problem as well.
System requirements says:


  Although PHP 5.3 is supported by Drupal 6.14 core and higher (see the release notes for 6.14), some contributed modules may not be compatible with PHP 5.3, and some PHP 5.3 configurations still show warnings with Drupal 6.14; work is ongoing to resolve the latter in #360605: PHP 5.3 Compatibility.


The issue linked in the requirements page is actually marked as fixed; this means that Drupal core is completely compatible with PHP 5.3 since Drupal 6.14.
