    Thank you…but I cannot access the WP admin…

    …is this my way out of RM issue or you suggest a better way:

    How to deactivate all plugins when not able to access the administrative menus?

    Sometimes it may be necessary to deactivate all plugins, but you can’t access the Administration Screens to do so. One of two methods are available to deactivate all plugins.

    Use phpMyAdmin to deactivate all plugins.

    In the table wp_options, under the option_name column (field) find the active_plugins row
    Change the option_value field to: a:0:{}

    Or reset your plugins folder via FTP or the file manager provided in your host’s control panel. This method preserves plugin options but requires plugins be manually reactivated.

    Via FTP or your host’s file manager, navigate to the wp-contents folder (directory)
    Via FTP or your host’s file manager, rename the folder “plugins” to “plugins.hold”
    Login to your WordPress administration plugins page (/wp-admin/plugins.php) – this will disable any plugin that is “missing”.
    Via FTP or your host’s file manager, rename “plugins.hold” back to “plugins”

    Hello,

    Thank you for contacting us and sorry for any inconvenience that might have been caused due to that.

    Please access your FTP or your CPanel’s File Manager, locate your website’s root directory and navigate to wp-content > plugins, and delete the folder seo-by-rank-math. After doing that, please try to re-install the plugin on your website and see if that works for you.

    Please note that all the data from the plugin will remain intact on the database in this process.

    Let us know how it goes. Looking forward to helping you.

    Thank you.
