Visual Editor, Revolution Slider and Essential Grid not working properly

Hello,

Just today I am receiving a notification bar on my site that is telling me the following plug-ins need to be updated to work with the latest version of this theme.
1. Revolution Slider
2. Visual Editor
3. Essential Grid

I’m very concerned because the portion of the TEXT BOX used in the visual editor has entirely disappeared. There is no option for fonts, icons, characters, etc. I use this most frequently. I have no idea what has happened because just yesterday it was fine and I was using it successfully. I have updated all plugins for my site more than once, and they are all the latest version. I’m very perplexed.

Please help! This is dire. Thank you so much!

Kind Regards,
Erin
