Empty screen when .po file loaded

Hi,

Thank you for this great plugin!
I have a problem with plugin translation – I made translation to Serbian (money-manager-sr_RS.mo) which is placed in wp-content/languages/plugins/.
Plugin name is translated, Home and Welcome is translated, but when I open Home there is nothing in window. If I click on Welcome, all the texts and import filed is there, but there is no css.

Please advise if you need more informations.

Thank you in advance!
