What causes warping?
There are two potential causes of a canvas panel that has been warped. To start if you’re  using a paint that is watery, it is possible for the paint to seep through the canvas and into the cardboard that’s attached to the back, this will then cause the canvas panel to warp. The next is, when using acrylic paint especially, the paint will tighten and "shrink" as it dries, which will cause the canvas panel that the paints on, to warp. 

How to prevent canvas panels from warping:
Before you begin working on your masterpiece, you should try out this artwork-saving  and easy trick , to stop the warping of your canvas panel. Using a foam brush, simply add an even coat of gesso on the back of the canvas panel to prepare for painting. After allowing it to dry, you can start on your art! 

Fixing a warped canvas panel:     
Don’t stress if the warping is severe, we’ve got an easy fix! Cover the back of your canvas panel with PVA glue, make sure to get all four corners and the centre. Then apply PVA glue to the back of a wood panel. Align both of them up and weigh down till the glue dries .
