my texts on widget get deleted

The texts that I type in my text widget disappear every time I browse away. I do click save and even wait for the save button to finish loading, but the texts just disappear.

I am currently using Destro as a theme and everything is running smoothly, until this happened.

The thing is, the WIDGET BOX remains where I put it and even show as a blank space on my website. It is just that the texts get deleted every time even after I saved them.
