How to fix blank screen on edit/add new chart popup in Visualizer
If there's an issue while you click on Edit Chart or Add New Chart, and nothing happens then there can be conflicts with various plugins, and/or themes that are currently active with your WordPress installation.
To fix this problem,
- Try disabling all the plugins, and/or themes, and revert back to the default theme (example: Twenty Seventeen).
- Check If the problem still continues. If it does, try re-installing Visualizer
- If it's working, Enable every plugin, one by one and re-activate your theme, and detect the part which was causing the issue.
