Hello,
A few people have reported this issue in the last couple of days but I was unable to reproduce the problem in a number of setups.
Is it possible for you to enable logs and send me whatever gets written out while you activate the plugin? Instructions for enabling logs are here: https://codex.wordpress.org/Debugging_in_WordPress This will help me know what’s wrong and what to fix.
Alternatively you can use the following SQL code in your console, to create the tables manually.
The above code assumes that your DB prefix is wp_. If it is something else, you will need to replace the table names.
