Hi @rakeshpositive
You really should open a new issue as this one is from 4 months ago and not related. Further, because it’s resolved already there’s a chance I will overlook it. You can open an issue and reference another issue by sharing the url if needed.

Meanwhile, that error message “checkSection is not defined” is not from MetaSlider as far as I know, so there’s likely another plugin running script on the settings page which is breaking everything else. you will have to identify that plugin and let me know so I can take a look (uninstall plugins one by one until the error disappears).
I have a feeling “$(…).destroy is not a function” is also not coming from MetaSlider.
Anyway, let me know what you find out.
