I encountered the same issue. The fix is to visit your site dashboard > Settings > Reading > Your homepage displays: Select “Your latest posts” and save.
Clear the browser cache and try editing. The issue MAY fix the issues raised here!
The issue is not from Yoast, it’s something that gets its way into your WordPress content files.
My site reported a critical issue this morning. During the investigation, I found the said files in the wp-content, well, nobody knows where those files came from.
This is the error message captured:
[04-Jun-2020 07:02:16 UTC] PHP Parse error: syntax error, unexpected end of file in /aaa/xxx/mm_html/yyyfolder/wp-content/plugins/helad.php on line 140.
So, I checked the said location and found two unusual files; admin_ips.txt and helad.php
Deleting those two files resolved the issue.
Question is, are those two files legit?
