Timthumb error?

Loading up the timthumb URL that way is supposed to generate that error. It’s missing parameters and you shouldn’t try to load that directly like that.

Timthumb can be a fun topic for discussion.

First, install this plugin an ensure you are not running a vulnerable version. Per your screen shot you are running 2.8 and I’m pretty sure that’s good. But why take chances?

Once that’s done, can you provide a link to your site?

But may I please know why I should provide a link of my site? Isn’t it possible to fix the error without seeing the site?

It absolutely is possible, and if you can’t share the link that’s fine.

It’s just that if the link were public we could see what’s going on such as how the img tags are setup. Getting the link often makes diagnosing the problem easier.

What theme are you using? Can you share the URLs (less the web server name) for those Timthumb images?

For example, like this:

http://example.com/wp-content/themes/elemin/themify/img.php?src=http://example.com/files/2012/02/80210004_DxO.jpg&w=75&h=75

Can you please provide your email-address? I can contact with you then

Nope! Sorry, but this volunteer support forum is the only place I can help.

That’s a commercial theme which is not available for downloading. There is nothing wrong with that, I use a commercial theme myself. And the theme I use uses timthumb as well.

Your best bet for support would be to use the support forums for that theme provided by that vendor.
