Well, weird thing, i can export the first Article content (Came: soluciones de automatización), but in this example, Vigitron i cannot export that one and most of the other articles

i used Template Gazette and all content was created using Articles.

I tried to Save Rows but it doesn't work for me.

I used to create all my content using Pages, but many months or years ago you (joomshaper support) suggested me to avoid Pages and create everything under Articles.

i tried yesterday to do what you suggested. Save each row of one of the pages, then o went to SP Page Builder, created a new Page, inserted my saved elements.

From there i tried to Export the whole canvas, and nothing... got the same error.

Any news about this?

Hello, could anybody please help me with this?

Thank you
