How to resolve this error?
Parse error: syntax error, unexpected '$od823' (T_VARIABLE) in /var/www/new/includes/src/Zend_Http_Response.php on line 1
It seems your compiled copy has some errors
Re-download lib/Zend/Http/Response.php (or maybe full lib folder, or maybe full Magento) for your Magento version
Disable compilation http://www.createhosting.co.nz/support/knowledgebase.php?action=displayarticle&id=49
Re-enable compilation (if wanted, not sure why would you want to do that, but that's your choice) When should I use the Magento Compiler
