An error has occurred. 500 Layout default not found.

 Hello Lefteris,

when saving the gallery, the error message "An error has occurred.
500 Layout default not found. "

I managed to insert 74 photos in parts, for the 75th one this error message is already displayed.

Joomla 4, PHP 7.4 and PHP 8

Thanks for the help.

Hello Lefteris,

unfortunately, I can't add a single other photo to the photo gallery. Maximum Input Variables = 1000.

Best regards
Martin

Hi Lefteris,

I set the parameter to 5000 and it already works.
Thank you.
