I’m trying to perform a bulk update of many pages rank_math_title custom fields according to specific requirements.
I’m doing it through the XMLRPC API and the only field that I’m updating is rank_math_title and it gets properly updated, but after doing this, in the header of the page I get an error
Warning: Invalid argument supplied for foreach()
on line 499 ofclass-paper.php
.Additionally, I also get an error when trying to edit rank math page options on page edit.
If I disable Rank Math Plugin, no error is shown and everything works as expected.
Any idea what the error might be and how I could fix it?
