I state that I have just installed the plugin I was doing tests: After saving the screen I get this error and I think the options are not saved. I wanted to ask for help on what to do. I am teestanding the plugin in a staging environment. In the attached image I inserted the warning that appears.
I hope for your help and I remain available for any information.
Hi, I will be glad to help. Can you try these troubleshooting steps first?
- Clear your browser cache
- Temporarily deactivate all plugins except Types, Views and Layouts
- Temporarily activate a default theme like Twenty Seventeen
- Test again. If the problem was resolved, reactivate your theme and other plugins, one by one, until the problem returns
