Here are the plugins :
– All In One WP Security
– Advanced Custom Fields PRO
– Contact Form 7
– Contact Form 7 Conditional Fields
– Custom Post Type UI
– Disable WP Theme Updates Advance
– Duplicate Post
– Elementor
– Flamingo
– Google Analytics Dashboard pour WP (GADWP)
– Google Captcha (reCAPTCHA) by BestWebSoft
– Redirection
– WP Rollback
– Yoast SEO
– WPS Hide Login
I tried to disactivate all of them EXCEPT Flamingo & CF7, and the error still there, if Flamingo is activated.
Same thing for the template.
Tell me if you want me to activate Flamingo to trigger the error.
Thanks for your answer.
