Can you rename the wordfence folder within wp-contents/plugins ro restore access to your site?

Then, can you tell me your wordpress version / php version?

Dave

thanks for quick reply.
I already deleted the plugin in the wp-contents/plugins folder. and now i have access again. I suppose the wordpress version is the reason. It is 3.6.
I will update everything accordingly.

thanks for support
