Hello folks,I' ve installed xampplite, a portable version of xampp in a prendrive. Then, i've created the database, user and so, and installed Joomla! (1.5.18), I started the server and It seems to works fine, altough it's a bit slow. Then i managed to install K2 (v 2.3) but  i get the following :
"Fatal error: Maximum execution time of 60 seconds exceeded in E:\xampplite\htdocs\Joomla\libraries\joomla\filesystem\folder.php on line 111" Suggestions needed!

I just changed the timeout in the php.ini file in the /apache/bin folder, and set it to 120 segs. Then, tried to install K2 once again, and it finally works. Sorry for the post, it was actually an apache issue.
