Hi! I have problem with uploading and cropping user avatars. In php error logs there’s a lot of this warning:
PHP Warning: transliterator_transliterate(): Could not create transliterator with ID "Any-Latin; Latin-ASCII; [\u0080-\u7fff] remove" (transliterator_create: unable to open ICU transliterator with id "Any-Latin; Latin-ASCII; [\u0080-\u7fff] remove": U_INVALID_ID) in /wp-content/plugins/buddypress/bp-core/classes/class-bp-attachment.php on line 292

Sometimes when I try to set user avatar there’s a bugs with cropping and I get message “There was a problem cropping profile photo.“.

I also notice that files don’t save properly on the server. There’s dash sign at the beginning and some files don’t have file format like jpg/png at the end.

Really please help, I don’t know how to fix this.
