I recently updated the plug in to 4.7 and I cannot upload images, It is the same escenario. The file size in Azure shows 0 Bytes, In wordpress sites apperars as broken Image and a message “Uploading to Azure… (1/9) ”
I’ve tried using the develop branch versión as you mentioned and I’ve changed the wpconfig file adding:
define( ‘FS_METHOD’, ‘direct’ );
Neither Develop Version nor configuration worked for me
??
Do you have any update?
