When trying to login to WordPress
I got this message instead:
(output started at public_html/wp-content/plugins/twitter/widget_twitter_vjck.php:171) in public_html/wp-includes/pluggable.php on line 896)
Which is interesting to say the least.
So after searching the Internet for a similar problem I found this WordPress support page:
Which suggested to look at the error and look for missing ?> (in this case they wanted the person to delete all content and add the ending bookends for the php code.
So I went to public_html/wp-includes/pluggable.php and found out that it did not have ?> for some reason. So I added the bookend at end of file "?>" and now I can login again.
I remember a couple of days ago I was trying to install a plugin and had some trouble. I eventually did get it installed, but I tried with several logins and different browsers. These actions may have caused WordPress to perform a file edit.
Anyway it is always good to have a backup, but if you need some WordPress help let us know.
