The Contact Form 7 plugin does not work for me, I understood for a long time, until I saw in the admin board a wordpress in the section “Site Health”:
The REST Api did not behave correctly The REST API is one way WordPress, and other applications, communicate with the server. One example is the block editor screen, which relies on this to display, and save, your posts and pages.
The REST API did not process the context query parameter correctly.
I turned off all the extra plugins, but it did not lead to success. The problem was gone only after replacing the topic with another one.
In fact, none of the forms plugin works
Help please solve this problem. https://100dorog.su/
