I have had many things on my website suddenly stop working:
* No longer getting user field values with RWMB_meta()
* I use WS Forms, and now when submitting forms it is very slow
* Other aspects of WS Forms that did work (eg show form validation) stopped working
* Entire taxonomy values disappeared, without any known reason why (I had to roll back)
All these issues I discovered from Thursday last week, and I have been testing by disabling my code and plugins (all except Elementor, WS Form, and MB AIO and Meta box), and nothing has worked. I now think that perhaps the update has impacted my current setup and would like to roll back to test. How can I do this?
I had similar problems, try disabling the Elementor Integration extension inside the Metabox AIO settings and see if that fixes it. It looks like they've fixed the Elementor integration issues in the latest version on github, but we'll have to wait for the next AIO release.
