This is usually an indicator for some code in the plugin or theme running too early. Translations should be loaded at the init action or later. Please see Debugging in WordPress for more information.

Consider a C++ class Document which holds a text content usi…
Consider a C++ class Document which holds a text content using a std::string (which internally utilizes pointers to manage its data) and an integer representing the document length. The class is represented in-memory with pointers facilitating dynamic memory management, while it is serialized to disk without using pointers.Here’s an outline of the class and its serialization method:class Document {public: std::string text; int length; void serialize(std::ofstream& out) { length = text.length(); out.write(reinterpret_cast(&length), sizeof(length)); out.write(text.c_str(), text.length()); }};Which statement best captures the distinction between the in-memory and on-disk representations of the Document object regarding pointer usage?
