Latest version broken

same with me,

after install this new update, my wordpress show this

The plugin generated 471 characters of unexpected output during activation. If you notice “headers already sent” messages, problems with syndication feeds or other issues, try deactivating or removing this plugin.

same here. exact same error message as above.

After updating plugin, I get this error whenever updating a post, page, anything:

Warning: Cannot modify header information - headers already sent by (output started at /home/.../public_html/wp-content/plugins/zopim-live-chat/accountconfig.php:20) in /home/.../public_html/wp-admin/post.php on line 235

Warning: Cannot modify header information - headers already sent by (output started at /home/.../public_html/wp-content/plugins/zopim-live-chat/accountconfig.php:20) in /home/.../public_html/wp-includes/pluggable.php on line 1121

You can hack a fix (PHP 5.3+) by replacing the style block at the top of accountconfig.php in the plugin with this:

<?php add_action('admin_print_styles', function() { ?>
<style type="text/css">
	.btn_orange {
		display: inline-block;
		width: 150px;
		padding: 10px 0px;
		background: #F38313;
		color: #fff !important;
		border-radius: 5px;
		font-weight: 700;
		font-style: normal;
		font-size: 14px;
		border: none;
		text-shadow: 0px -1px 1px rgba(0, 0, 0, 0.2);
		text-decoration: none;
		text-align: center;
		border: 1px solid #E37A13;
		box-shadow: 0 1px 1px rgba(0, 0, 0, 0.1), inset 0 1px 0 rgba(255, 255, 255, 0.2);
	}
</style>
<?php }); ?>

Hi webaware,
thank you for your suggestion, the update has been rolled out.
Appreciate your help!

@bencxr: that code works OK for PHP 5.3+ but will break on PHP 5.2. I suggest you refactor it to use a named function, not a closure. Otherwise, you’ll get a new crop of “doesn’t work” reports from people still hosted on old, obsolete, unsupported versions of PHP (and there’s lots of them!)

cheers,

@webaware, yeap did a refactor to register and enqueue the styles. Should work for all versions now. Thanks you for your help really appreciate it.
