Hi everyone,

I just installed a wiki on a shared server and got the following Warning msgs, can anyone help with that, what do they mean? Should I do something?

. Warning: A value for session.save_path has not been set in PHP.ini. If the default value causes problems with saving session data, set it to a valid path which is read/write/execute for the user your web server is running under.

. PHP's memory_limit is 32M.

. Couldn't find Turck MMCache http://turck-mmcache.sourceforge.net , eAccelerator http://eaccelerator.sourceforge.net , APC http://www.php.net/apc or XCache http://trac.lighttpd.net/xcache/ ; cannot use these for object caching.

That last msg keeps repeating itself for 10-15 times ..
