I have a MB Frontend Submission form that among other info requires a file upload (I'm asking for bio in PDF format). Everything is working fine as long as I'm logged in, I see my file in the backend (using MB Admin Columns). However, when I test my form when I'm logged out of WordPress, file upload is not processed. How can I enable file uploads in my form for non registered users?
It is possible that there is a conflict between Meta Box and another plugin. You can try to deactivate all plugins except Meta Box, MB extensions and switch to the standard theme of WordPress then re-check this issue.
Thank you for your fast reply. Disabling all plugins and switching to 2022 theme did work! To pin point what was causing the problem, I activated the theme - tested the form and it still worked. Now it also works with all the plugins active (I did enable plugins one by one after each form test). Looks like it needed some kind of restart.
Thanks again for your fast reply and great insights into this issue.
