Hi Everyone,
We have been working on Joomla for a while using Xampp and everything was just fine. Recently we installed Windows 7 in our computer and then we re-installed Xampp.
Our present configuration is:
Windows 7
Server: localhost
Joomla: 1.5.15
Apache: 2.2.11
XAMPP: 1.7.0
MySQL: 5.1.3
PHP version 5.2.8
Directory Permissions: everything is writable
We found these fatal errors in Joomla backend:
Warning: call_user_func_array() [function.call-user-func-array]: First argument is expected to be a valid callback, 'JCacheStorageapc (1)::test' was given in C:\xampp\htdocs\Joomla15\libraries\joomla\cache\cache.php on line 143

Fatal error: Cannot redeclare class JSessionStorageDatabase in C:\xampp\htdocs\Joomla15\libraries\joomla\session\storage\database (1).php on line 135
What should we do to fix these problems?
Thanks
