Hello,

I have just recently installed and deployed a concrete5 instance from my local environment onto my server. I am using a custom theme.

When I navigate to the site I see a blank page and the logs show the following error:

"[Fri Nov 07 15:53:19 2014] [error] [client 38.122.241.106] PHP Fatal error: Undefined class constant 'Doctrine\\Common\\Annotations\\DocLexer::T_IDENTIFIER' in /var/www/vhosts/tilsonconsulting.com/DEV/bhd.cms/concrete/vendor/doctrine/annotations/lib/Doctrine/Common/Annotations/SimpleAnnotationReader.php on line 46 "

Would anyone be able to help?

Thank in advance,

Hesam
