I am trying to download all posts from a particular category. It seems I am only able to export the first page (20 posts) and not all posts with that category. Is there a way to export and download ALL posts from a particular category without having to go through 15 pages and repeating the process that many times?
Yes, you can change it to by clicking on the “Screen Options” on the top right and then typing the “Number of items per page” to whatever number you want.
I have the same problem. Changed the Screen option to 50. Selected 3. Set to generate .docx files. Generated .zip file.
Using Windows 10. The zip file that is generated and downloaded will not open with error message that it is not a ZIP file. Tried with three different Zip programs. Same results.
What can I do differently to get this to work?
