Problems with Fusion Builder after update to 5.0.6.

After updating to version 5.0.6. Theme Avada I haven’t been able to upload any images or to modify the pages. In the pages section, the text is not accessible nor the add media button. The following text appears: Failed to initialize plugin: fusion_button

The fusion builder page goes green and I cannot see any of the options.

I already have in use the classic editor.

System status gives the following option: is this necessary to be done manually? Normally the updated have gone through without any probelms.

Avada 5.0 Conversion:
Rerun Shortcode Conversion from version 3.9.3 to version 5.0 manually.
