[Résolu] WPML Multilingual CMS critical error on activation

Contact me on: krzysztof.wieczorek@kubara.pl

I'm experiencing a critical error when trying to activate the WPML Multilingual CMS plugin. The activation fails immediately with no specific error details shown in the admin panel.

Before the critical error occurs, I see these dependency warnings from other WPML modules:

WPML Media is enabled but not effective. It requires WPML in order to work.

WPML Sticky Links is enabled but not effective. It requires WPML in order to work.

Please activate WPML Multilingual CMS to have WPML String Translation working.

Then, when I try to activate WPML Multilingual CMS, I get:
"Wtyczka nie mogła zostać włączona, ponieważ spowodowała wystąpienie krytycznego błędu."
(Plugin could not be activated because it triggered a critical error.)

I haven't made any unusual changes—just attempting standard activation.
