Here is my question in stackoverflow: https://stackoverflow.com/questions/26771070/an-error-occurred-while-processing-this-directive-after-upgrade-magento-from-1.
I just updated magento from 1.5 to 1.9 by this way: – Go to magento connect and install package: http://connect20.magentocommerce.com/community/Mage_All_Latest.
After that, I got an error like this: CONNECT ERROR: Package community/Mage_Core_Modules 1.9.0.1 conflicts with: community/Mage_GoogleShopping 0.3.5, community/Ansyori_Autotrans 0.1.0 Package 'Lib_Google_Checkout' is invalid Empty package contents section
And then, when I go to my website, it always gets this error: [an error occurred while processing this directive]
I try many ways: reset permission, change User name but nothings change. Anyone can help me ?

Do you have a backup before you upgrade?
If you do, I suggest that you roll back and attempt it again but this time try to do it step-by-step from 1.5 to 1.6 to 1.7 to 1.8 and finally to 1.9 instead of going directly from 1.5 to 1.9.
What I suggest is for you to create a staging store and attempt the upgrade from there.
You should also take multiple backups to make it easy to roll back if required.
After taking your backup, attempt the upgrade from 1.5 to 1.6 and check if everything works fine. If it does, continue step-by-step until you are at 1.9. If something broke in between, find out if there's any code changes which may affect your theme or extensions which are not compatible and attempt to correct them first before you continue.
