[SmartCrawl Pro] Issue with SmartCrawl Pro

Greetings!

We are currently using your plugin smartcrawl in our website https://media3w.com. However it started malfunctioning since the last update. Any changes in keywords when we edit a page does not save anymore, the smartcrawl options are currently working fine but when we edit a single page adding or changing keywords, these are not saved.
May you be able to assist us or help us with this? We urgently need to fix this issue.

Thanks in advance
