I'm having trouble with a Wordpress site that I sold. Basically I get this message that displays as text before the header at the homepage: Warning: unserialize() expects parameter 1 to be string, array given in /home/bestbuyk/public_html/wp-content/plugins/maxblogpress-ping-optimizer/maxblogpress-ping-optimizer.php on line 95 Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at /home/bestbuyk/public_html/wp-content/plugins/maxblogpress-ping-optimizer/maxblogpress-ping-optimizer.php:95) in /home/bestbuyk/public_html/wp-content/plugins/wordpress-automatic-upgrade/wordpress-automatic-upgrade.php on line 110 Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/bestbuyk/public_html/wp-content/plugins/maxblogpress-ping-optimizer/maxblogpress-ping-optimizer.php:95) in /home/bestbuyk/public_html/wp-content/plugins/wordpress-automatic-upgrade/wordpress-automatic-upgrade.php on line 110 And when I try to login to Wordpress to deactivate the plugins I can't, I get just the following message and no login screen Warning: unserialize() expects parameter 1 to be string, array given in /home/bestbuyk/public_html/wp-content/plugins/maxblogpress-ping-optimizer/maxblogpress-ping-optimizer.php on line 95 Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at /home/bestbuyk/public_html/wp-content/plugins/maxblogpress-ping-optimizer/maxblogpress-ping-optimizer.php:95) in /home/bestbuyk/public_html/wp-content/plugins/wordpress-automatic-upgrade/wordpress-automatic-upgrade.php on line 110 Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/bestbuyk/public_html/wp-content/plugins/maxblogpress-ping-optimizer/maxblogpress-ping-optimizer.php:95) in /home/bestbuyk/public_html/wp-content/plugins/wordpress-automatic-upgrade/wordpress-automatic-upgrade.php on line 110 Warning: Cannot modify header information - headers already sent by (output started at /home/bestbuyk/public_html/wp-content/plugins/maxblogpress-ping-optimizer/maxblogpress-ping-optimizer.php:95) in /home/bestbuyk/public_html/wp-includes/pluggable.php on line 770 I hate to, but I could try and rebuild the site. I just thought I'd ask first Thanks
Was it working before? Basically what's happening is the code already sent something and it's trying to modify it again. Have you tried deleting the plugin in the folder? Try to back it up first
According to me you might have tried to upgrade wordpress and there are some plugins you had in your blog which might not be compatible with the latest version of wordpress. And at the time of automatic update of wordpress it might have happened that your database might have got corrupted.
Yeah there has been several updates to both wordpress and the plugins, but the plugins were compatible with the wordpress version that was installed. I guess maybe the customer updated one but not the other. It seems that it affected some sites, but not all. The trouble is I cannot login to Wordpress to deactivate them, so right now I'm thinking my only other option is to delete Wordpress and rebuild the site Thanks
