Hosting support

Does anybody know of a hosting company that supports Drupal and has Tomcat servers?

Hi,

I decided to try a shared account at Midphase, based some favorable reviews here. I setup 2 domains, one is an out of the box D6.6 core only install with nothing but one "come soon" node added. The other was an existing site, upgraded to 6.6 in the migration. Both sites ran great for about a week with many edits on the busy site, then the very same morning, both sites are having session problems. They still serve pages to anonymous users but when I try to login under any account I get "Access denied. You are not authorized to access this page." -- even on the core-only install.

In my mind, to affect both domains at the same time, something changed on the server. A php library or something. Midphase says nothing changed on that box and say they can't help without knowing exactly what Drupal needs for php. Obviously there are scores of problems reported about this problem here and I've tried several of the fixes to no avail. But is there a list of exactly what's needed for PHP or possibly which particular PHP changes trigger these session/login problems?

Is anyone else experiencing this at Midphase on their new servers? Again, it broke overnight on two different D6 installs.
Apache version 1.3.41 (Unix)
PHP version 5.2.6
MySQL version 5.0.51a-community

We have a development environment running PHP version 5.2.4 - when we moved our site over to production environment they were running PHP 5.1 - caused several issues. When they upgrade the version to PHP 5.2 we are no longer able to see the site. We get a done in the bottom bar left corner and a blank white browser. We are able to login using myadmin. Any help much appreciated.

Here are the PHP configuration/error logs - The line the sysadmin is most worried about is: "Trying to get property of non-object in /var/www/carespace/trunk/drupal/core/modules/locale/locale.module on line 175"

I am shopping around to find an upper level web host with specialization in Drupal and good support. Any suggestions?

Thanks

Hey guys:

I put up a drupal sample site on my computer running windows XP, the server environment of which is WAMP server (Apache and MySQL). Now I am migrating my sites over onto Linux environment where same Apache/MySQL are running. I had an attempt where:

-whole drupal database was drumped and then imported into one on Linux.
-All files from original sites copied to and overwrite ones under Linux.
