I installed WordPress multi-site on LEMP (Nginx). All of WordPress functions and plugins are working well but any contact form plugin is not working!
The mail which is sent by any contact form plugin is arrived me. However there is no success screen at all.
How can I fix it on Nginx?
NOTE: I deactivated cache plugin and minify plugin. And SMTP settings is working well too. I tried everything related to WordPress. It may be related to php ini?
I tried to install Contact-form-7, Simple contact form, Pirare forms etc.
