Hi @keraweb sorry for my late, late, late reply. Your answer is the fix, thank you verry much!
Little update;
If i use at Order by: “title ASC” and at Where: “t.post_title LIKE ‘%A%'” it shows everything in asc with the letter A in it, so i think i’m getting in the right direction.
I tried to use $first_char ‘%A%’ in ‘Where’ but that doesn’t display something (i have also no idea if what i tried is possible, this is not my cup of tea)
