I'm sorry to hear about your problems.
I know, it won't be any consolation to you, but we do run 2.4.4 on the XOOPS Site, and don't have any problems (the only issue was to adjust our theme, as 2.4.4 exposed couple of issues is our CSS files).
Unfortunately, I cannot help you on your local PC, but if you upload it to a Web server, I'll be glad to look into it.
1) I don't know why your Cache file has not be initialized. Maybe the folder has wrong permissions?
2) Reg. debug info change the /include/common.php around line 237:
if ($xoopsLogger->activated) {
$level = isset($xoopsConfig['debugLevel']) ? intval($xoopsConfig['debugLevel']) : 0;
if (($level == 2 && empty($xoopsUserIsAdmin)) || ($level == 1 && empty($xoopsUserIsAdmin))) {
error_reporting(0);
$xoopsLogger->activated = false;
}
This will show the debug messages only to the Admin.
3) I am not aware of any problems with Oxygen.
What PHP version are you using?
Can you check on WAMP Server locally, or on a Web host, if you are getting the same issues?
