Hello,
perhaps somebody could help and give me a hint. I transfered a Website to Xampp. After updating the theme “Landio” i get a critical failure from the “batch” filter (twig):

grav.CRITICAL: The "batch" filter expects an array or "Traversable", got "NULL". - Trace: #0

Not only you didn’t provide any context (was it admin, main page, other page with some custom theme template?), you even managed to remove part of the error, where I believe it actually showed where the error was

Thanks Karmalakas for the advice
The problem is solved.
it was the failure with /modular/text.html.twig connected with the line

{# {% for row in page.header.text|batch(2) %}

i corrected my twig. Now theres is no failure
Thanks again
