Hello support Stackideas

First of all I apologize for posting this topic. I searched everywhere for a solution but no luck.

I have a problem that is not related to extensions of stackideas or another. It's about the joomla administration on the creation and editing articles. The issue is when selecting the main picture for the article in the frontend.

I have no issue add article and imagen in the backend, only in the frontend.
