Firstly: What you posted isn’t “codes”, these are plain error messages. Code is PHP or HTML or CSS or JavaScript.
Secondly: Something must be wrong in the dfblog plug-in or you have posted a reference to this plug-in (i. e. a call to the plug-in in your template(s)) while the plug-in isn’t present or activated.

Sorry VIPStephan,

Yes, I know now that it is indeed an error message. Do you know what I can do to correct this? any suggestions on how I can go take this down or correct from my cpanel or where ever I can go to correct this?

Thanks

Download the dfblog plugin, and upload it to your wp-content/plugins/ directory. Somehow it was installed into the system, so its looking for it, but the files must have been moved or deleted.

Thanks gnomeontherun.... I will try and do this now and hopefully I can do it correctly...

Thanks
