    On my site I have multiple blogs and two of them use the plugin Revolution Slider version 5.1.1. One of these sites no longer needs this slider but I cannot deactivate the plugin. When I do I get this error message:
    Warning: in_array() expects parameter 2 to be array, null given in /storage/content/.../admin/revslider-admin.class.php on line 389

    Then I tried to disable the plugin by updating the option_value in wp_xx_options table as described here: https://www.ostraining.com/blog/wordpress/disable-a-wordpress-plugin/. When I do that the value is updated for less than a minute. When I refresh the page in phpmyadmin the value is reset to the original! How is this possible!?

    On the network level I am using W3 Total Cache and WP-Optimize to speed up the site. Can this case the update database problem?

    Also, I am unable to update the Revolution Slider plugin because it is a commercial plugin and I have lost the license key. It was purchased by another user who is very hard to get in contact with.

  • You can also remove the plugin via ftp by deleting it from the wp-contents/plugins.

    This may leave some residue behind in the database, but will get the plugin removed.

    As I mentioned in my question, there are one site that uses the plugin so I am unable to remove the plugin.

    My apologies, I miss-read your post. That does make is tricky if you are gambling with losing a licence key.

    Have you tried to contact support for the Revolution Slider? https://www.themepunch.com/support-center/
