Hi dear user.

Thanks.

What the file

Hi dear user.

Sorry for so late response.

You need to find and edit this file – gallery-album/includes/admin/js/post_page_insert_button.js

On line 39 you will find such code

file: document.location.origin+ajaxurl + '/?action=wpdevart_gallery_post_page_content&gallery_id='+getAttr(title,'gallery_id')+'&album_id='+getAttr(title,'album_id')+'&theme_id='+getAttr(title,'theme_id')+'&order_type='+getAttr(title,'order_type')+'&lost_ids='+getAttr(title,'lost_ids')+'&popup_albums_themes='+getAttr(title,'popup_albums_themes')+'&popup_themeid='+getAttr(title,'popup_themeid'),

there is such code in that line

/?action

You need to change it and type this instead –

?action

You will find the same code on line 84, do the same action there.

This should help.

Thanks.
