Hello,
I have also BIG problems with the new (updated) cornerstone and X and need help urgently!!!
Edit: I could resolve it by delete the X and re-install it, now there is only a small problem: my sidebar don’t shows up on my pages!
the Problem was:
All Links to the blog posts don’t work anymore. There is only this message on a blank page:
“Fehlendes Template. Eigenständige Themes müssen über eine index.php Datei verfügen. Für Child-Themes muss ein Template-Header in der style.css angelegt werden.”
Translated in english: “Template is missing. Independet Themes must have an index.php file. For child-Themes there must be added a template-header in the style.sss”
The Links in the masonry are made with The grid or Essential grid. All plugins and also WP is the newest.
I don’t know NOTHING about css and code, and I NEVER created a child theme!!! so PLEASE can anybody help me? its VERY urgent!
Also I wonder where the selection of the type of page is gone (e.g. blank container, with or without header / footer etc.,)there are no mor selectable.
Thank you, greetings from Switzerland
Nicole
