 * Hi,
 * I have tested in my environment with the following specifications:
    - WordPress version 5.4.15
    - Current plugin: FireBox (version 2.1.15)
    - PHP version 7.4.33
 * However, an error occurred: `Call to undefined function FPFramework\Base\register_block_type_from_metadata()`
 * This is because the `register_block_type_from_metadata()` function was introduced
   in WordPress version 5.5.0.
 * I hope the author can set the minimum supported WordPress version to 5.5.0 to
   avoid confusion.

 * Thanks for letting us know and sorry for the inconvenience.

 * I am marking this as solved.
