This was caused by an elegant_themes feature.

Problem is not within the WP codebase.

This topic is NOT resolved, but no one is responding. I am going to create a different post to resolve this.

https://www.ads-software.com/support/topic/apply_filters-returns-a-non-empty-string-when-the-value-is-empty?replies=1#post-5229290

And now I have explored and seen that the line that is likely to be the challenge is the resulting apply_filters line.

$title = apply_filters( 'widget_title', empty( $instance['title'] ) ? '' : $instance['title'], $instance, $this->id_base );

The question I have is why would the apply_filters function return a single space when the value after the ? is clearly an empty value.

Any reason why that would happen?

Sorry for the reposts – looks like the caching had some issues.

Additional debugging:

• I have turned off all of the plugins
• I have checked and the value of '' is given to $title
• When I swap empty( $instance['title'] ) for empty( $title ), the code works (no titles show on the text widgets)
• When I print out $title, I see a space.
• On another instance of WP, I have no problem with this code.

Help?

J – I love the idea – but I will eliminate the CSS file and you think it will work then? It was defaulting to 600×131 for some reason.

J – thanks for the response. The problem I now have is that the size of the meteor-clip class is nto set correctly. I had to manually set it in my etra CSS. Any idea why?

You can see the action when you comment out line 29 in style.css – any idea why?

I fixed it with a force of the CSS for Chrome, but in Firefox is it weird.

I think there is a bug in the code.

I replaced the copy I had with the newest version from google code. Right now, I think we are having database problems.

Funny – I have TimThumb as well.

Sadly there are no files that match those names on the server which is why I summer I have been hit.

I will try the plug in. Any other advice?

Wow. It worked. I wonder why. Could it be some of the PHP code I have in the widget?

What made you suspect the PHP widget?

I will try. The Original Investigations widget is the ExecPHP widget.
