WPML compatibility (warning)
I seem to experience some WPML-related issue, my site is bilingual - NL and FR.
NL is the default language and there are no errors/warnings, but as soon as I start using FR version, plugin Query Monitor
reports php's warning:
array_walk() expects parameter 1 to be array, null given
