I am trying to upgrade step-by-step to 2.2. But when upgrading from 2.0.7 -> 2.0.9.2 I get a blank page. When turning php-bugging on I get this message:

Fatal error: Call to undefined function: smarty_core_write_compiled_resource() in /home/dreng/public_html/gimle/class/smarty/Smarty.class.php on line 1423

Could anyone plz help??


P.S. I love XOOPS but upgrading seems almost impossible. I have tried to upgrade eight times and only succeded once... Lack of usability there: even though I am a bit stupid when using a php-portal, I believe I am not the only one.
