Problem:
The customer reported that the Toolset Maps block is showing the error message 'This Block has Encountered an error and cannot be previewed'.
Solution:
Guided that there was a console error related to the missing Google Maps API key. The Google Maps API key was set in Toolset's map settings, but not in the Divi theme.
Disabling the "Enqueue Google Maps Script" option from WP Admin -> Divi -> Theme Options -> General fixed the block error.
Image Slider block, blinks when the image is loaded. Is there a way to pre-load the images?
Solution:
Use the View slider method to add the slider instead of the image slider block. Then you will have an option inside the pagination section for Ajax loading. Please check the documentation.
