Had this problem on a local install with 4.1 also.
This worked for me:
in wp-includes/update.php
go to line 24/25 which reads:
`if ( defined(‘WP_INSTALLING’) )
return;`
and re-format onto one line like so:
if ( defined('WP_INSTALLING') )return;
I very much doubt this is doing anything in particular, you could more than likely format any line you wish, but the action of saving it appears to fix the problem.
Hi, you can change the line to `}
$content = mb_substr($content, 0, $first_space_pos, ‘UTF-8’) . ‘<a href=’.$content.’> read more </a>’;
}`
Of course you can change the text ‘read more’ to whatever you like.
