After activating wp-project I got this message on the top of my wp admin panel:
Warning: unserialize() expects parameter 1 to be string, array given in /home/morph/public_html/four/wp-content/plugins/wp-project/wp-project.php on line 53
Warning: Cannot modify header information - headers already sent by (output started at /home/morph/public_html/four/wp-content/plugins/wp-project/wp-project.php:53) in /home/morph/public_html/four/wp-content/plugins/xlanguage/xlanguage.php on line 224
I don't tested the plugin features. Wp Controlpanel works fine but the message is on every admin page. Any ideas, how I could fix this problem? I'm not a good programmer...
