Error into the second tab

I've not been able to find an answer in any threads to my problem.

I have set up twotabs using NewsProGK4 and Tabsw GK4. The first tab is showing perfectly and uses a Joomla article as the data source, the second tab however adds the "Error: No articles to display" at the top of the article that it links to. The settings of the second tab is an exact duplicate of the first tab - I'm just linking to another Joomla article in the data source.
The "First New Number" parameter in the data source settings has been set to 0.

Any help would be appreciated please.

Please make sure that any articles exist on this selected categories and check whether option show only featured items is not enabled in News Show Pro configuration.

Hi There

Thanks for trying to help. The module is linked to Joomla articles so I used an article ID to link to - the article exists and is published. The "Frontpage Only Items" is set to off. As I said, I made a duplicate of my first tab which works perfectly and just changed the article id. Could there be something in the article itself that triggers this problem?

This matter is urgent and there has been no response for a week - is there anybody out there who can help? I am using this module in Tabs, the module does what it's supposed to do, but it also displays an error message above the article in one of the tabs. I've checked all my parameters and configuration settings. I've used the same settings as in the first tab which displays perfectly, I only have a problem with the module in the second tab. This is very frustrating and the homepage looks bad because of this.

No, article itself can cause problems it is surely your configuration issue but probably without checking your back-end it is impossible to resolve. As you can see one module is wokring, another not. This is for 100% not extension issue but your wrong configuration. Please send me admin details via PM becuase I don't see any other way to check this.

Thank you - I have sent you a pm.

Still don't get any message from you, please let me know when you sent details.

I sent a private message just now again.
