Sometimes my wordpress website throws this error, does anybody have a similar problem... Would it be a problem in the htaccess file?
Warning: Cannot modify header information - headers already sent by (output started at /home/content/95/9830495/html/wp-content/plugins/WP-Client/wp-client.php(22) : eval()'d code(1) : eval()'d code(1) : eval()'d code(1) : eval()'d code(129) : eval()'d code:2) in /home/content/95/9830495/html/wp-includes/pluggable.php on line 881
My first thought is to make sure your site hasn't been hacked. I don't know enough about the inner workings of Wordpress to be sure, but any repeated use of eval() (or even just any use) smells of someone injecting unfriendly code into your site. Maybe reinstall Wordpress and any plugins, and make sure you add the wordpress firewall 2 plugin or something similar to help prevent attacks -- and of course reset all passwords associated with the site.
Hopefully that's not the issue, but pending someone who knows otherwise adding something here, that would be my approach (unless I really felt like wading through the Wordpress source code to see what it was doing in the files called out in the error message).
