Hi,
I attempted to migrate from Toolset to Metabox. The CPT, custom fields, and Relationships were successfully migrated. However, the single page template for the CPT appears to be broken. I tried resetting the permalink settings, but that page returns a critical error and is inaccessible. I cloned the site twice and tried again multiple times with the same result. I changed the theme and disabled all plugins, but the issue persists. Interestingly, when I disable Metabox AIO, the site works fine. However, enabling the plugin again breaks the site.
I can provide the credentials of my website for you to examine the issue. Please help.
