Key column ‘option_id’ doesn’t exist in table

[ad_1]

Somehow, your wp_options table has a missing key.

Issue this MySQL data definition language (DDL) statement

ALTER TABLE wp_options ADD UNIQUE KEY option_id(option_id)

and your problem should be fixed.

I can’t begin to guess how that key got lost, sorry to say.

If you have WP-CLI support you can issue that DDL with this line of a shell script command:

wp db query "ALTER TABLE wp_options ADD UNIQUE KEY option_id(option_id)“

Or you can use phpmyadmin or some other SQL client program.
