I am having a rather serious problem with my magento installation.
when trying to put through a test order i note that suddenly my checkout is no longer working
i get the error
Fatal error: Undefined class constant 'CHECK_USE_FOR_COUNTRY' in
/public_html/includes/src/Mage_Payment_Block_Form_Container.php on
line 65
I have not actually done any changes to that file.
can anyone help
Best Answer
include/src/ is where magento places the 'compiled' classes. Do you have (or want) compilation mode to be enabled?
Did you maybe install something, or recently clear the cache? Disable compilation, clear cache, then re-enable
Check outcome:
Now clear your cache, and re-enable compilation if you want to use it again. (but it could be possible that something got installed that does not work with compilation - which is an entire new question ;) )
