The error? the translate action produced by the echo with $oitar variable in line 308 of file user-avatar.php with setlocale() in locale with a comma as a decimal symbol. (French, German, Spanish, Italian)
In Spanish the decimal symbol is a ‘comma’ (,), not a dot (.) but in computer languages (included php, of course) in ALL idioms has dot (.) . The setlocale(LC_ALL, ‘es_ES’); translate the number in $oitar to spanish decimal symbol, for example:
$oitar=1.28543; echo $oitar; /* this return 1.28543 (in php is recognized as float when operate it)*/ setlocale(LC_ALL, 'es_ES'); echo $oitar; /* this return 1,28543 (in php is recognized as string when operate it, then php try to transform this to float, php can't translate the comma, then return the number <em>before</em> comma = one (1). */
When the plugin use wp_crop_image() for crop the image, the user selected width has transform to the final width only if $oitar > 1 (line 394 of same file), this is math relation, 1,28543 is translate as 1, then 1>1 is false.
The ideal: Zend will MUST solve this, i like use echo for print in screen, not for format! If i like format i may use number_format()!
The reality: In the start of the function user_avatar_add_photo_step2 in line 246 of the same file i can put:
an this solve it.
