broke my WP theme customizer

For some weird reason, installing WCPS broke my wp theme customizer so it would not save anymore.

A fix was illusive. Even after I removed the plugin, I still could not save in my theme customizer.

I had a backup, so I restored a backup (from before WCPS) and recovered my theme customizer saving capability.

The slider was nice. I didn’t want to lose it. So, I reinstalled it, and the same thing happened again.

The process was repeated one more time with the same results, and then, forced to choose the customizer or the product slider, I chose the customizer. (I feel ashamed. :))

Just letting you know in case the information is important.

The site is all up-to-date, Genesis theme with LT-BBQ child. Lots of plugins. I disabled and reinstalled one by one, and yours was the only one that made the customizer stop saving. Does the plugin change any file permissions on install?

Anyhow, I gave up. Except for this, I really liked the wc product slider!
