Problem with SEO YOAST plugin
-
Hello,
I have been using the free version of the Yoast SEO plugin without any issues. Recently, I purchased the Premium version. After a successful installation, I was prompted to perform SEO optimization, which failed with the error message: “error parsing the response to JSON.”
As a result, I canceled my subscription, uninstalled the Premium version, and completely removed Yoast. I then reinstalled the free version, but the error persisted during the plugin activation even though it was the free version of Yoast SEO. These lines appear in the WordPress editor at the top:

- Reinstalling the plugin
- Deleting files in the wp-content directory
- Clearing the cache in WP Rocket (which I use)
- Clearing the browser cache
Despite these efforts, the issue still persists. After contacting support, I was directed to this forum.
I would appreciate clear and understandable advice, as I am not a programmer.
Thank you, and have a great day!
