this type and there are plenty of them

Answer 1

In fact, yes, this is an error from the installed plugins in the system which one you can try to guess and deleting all files from the /engine/cache/system/plugins folder and disable the plugin by reloading the page with clearing the cache, and when you understand what the error of this plugin is, contact the owner to ask for updates to your version, since it is clearly a dle update with a non-supporting plugin, just like that, changing the structure of the database does not happen
