Slider not rotating after wp update

Hi there! Well, I updated Wordpress today (to Version 4.1.2), and imediately after it was done, my slider became a single image, it shows no navigation dots under it and it is not rotating the featured posts I selected. I double-checked the IDs and configuration (it is set to 4 slides), I have even disabled and re-enabled the entire slider, no luck. Any ideas on what could be wrong? Some problem at my end or could it be some incompatibility issue with the new wp version? Thank you everyone :)
