No problem Geoffrey, thank you !
“asort” works wonderful, icons appear in alphabetical order.
In other hand, when i put the code in function.php i got blank page.
I tried to past it before the end in case of space at the end of the file could create this issue but nothing changed. Anywhere i paste the code i got blank page.
I kept the file this way for the moment since it works but if you have any clue or advice to avoid this i will very happy :))
Many thanks anyway for you reactivity and this great plugin. And, sure, about the review ! ??
