Hello Martin

Which addon are you using? Please share more information on this.

Best regards

(Addon in PBpro, Bloglayout)

I think there is only one AddOn that shows articles in Blog Layout or am I mistaken?

AddOn "Joomla Article" -> some category -> article. blog layout

If no article in that category exists, it displays "No item found!". How can I disable that?

Please use this CSS to Template Options -> Custom Code -> Custom CSS

.sppb-addon-wrapper .alert{
    display: none;
}

Can I show a custom Text?

Yes, you have to override this language string:

COM_SPPAGEBUILDER_ADDON_ARTICLE_NO_ITEMS_FOUND="No item found!"

Can I show an category-based text?

Category-Blog 1: "No items found"

Category-Blog 2: "Nothing to see here"

Category-Blog 3: "No news"

DOES ANYONE HERE ACTUALLY PROVIDE REAL TECHNICAL SUPPORT???? I'VE BEEN GOING BACK AND FORTH FOR MORE THAN A MONTH AND NOT A SINGLE THING HAS BEEN RESOLOVED!!! ONLY MORE DAMAGE!!!! WHERE IS THE SUPPORT TEAM???

Anthony Grinblat, inappropiate. The support of Joomshaper is excellent: Fast, competent and (with one exception) very very friendly.

MY ISSUE HAS BEEN GOING ON FOR MORE THAN A MONTH AND THEY REFUSE TO ADDRESS THE ISSUE...SO NO, THEY'RE SUPPORT IS NOT "EXCELLENT"!!!

Martin,

Sorry, showing category based is not possible. Actually, nobody wants to develop for "no items found". Everybody develops to show the item. I think it is not practical because in the end you want to show the articles.
