I am just done with the installation and creating tables....I am at the step of loging in as admin. I have uploaded all files of /blog to my root directory. Installation went fine, but when I put
http://blog.falaj.net/admin
I got:

Warning: main(/hsphere/local/home/mmazroui/blog.falaj.net/b2evocore/../plugins/plugin.class.php): failed to open stream: No such file or directory in /hsphere/local/home/mmazroui/blog.falaj.net/b2evocore/_class_plug.php on line 18

Fatal error: main(): Failed opening required '/hsphere/local/home/mmazroui/blog.falaj.net/b2evocore/../plugins/plugin.class.php' (include_path='.:/usr/local/lib/php') in /hsphere/local/home/mmazroui/blog.falaj.net/b2evocore/_class_plug.php on line 18

How could I fix this, please.
