Hi,
For some reason I am getting " Error 404 - Not Found" when trying to open Pro.
I recently made these changes, which may be the reason:
- SSL was not activate on the entire network, and I activated it. After doing this, I started getting errors while creating new pages (The error was: “Publishing failed. The response is not a valid JSON response.”).
- To fix this problem, I switched the permalinks to “Plain” and it solved the problem, however, I leaned that this will create a SEO problem. Then, I installed the WP Classic editor, and it solved the problem, and switch the permalinks to “Post name,” but this time when I try to edit content with Pro, I am getting the 404 Error
I would greatly appreciate if you can help.
