OK, Let’s start. Although I am not sure but this may help you.
Login to your site’s using FTP or host(cPanel) file manager.(Here I am using Filezilla)
Browse to the “wp-content/plugins/” folder.
Find the folder of the plugin you want to disable.
Rename the folder to some other name.
For Ex: I want to deactivate “akismet” plugin then i rename it as “akismet_old”
Now try to login wp-admin.
Let me know the status.
If above method didn’t work then follow this one.
I am trying this one in my localhost.
Before doing something first take a backup of your database.
Login to your database using phpMyAdmin.
Then Click on the database.
Now click on SQL and run below query.
SELECT * FROM wp_options WHERE option_name = ‘active_plugins’;
Note: “wp_” is the default prefix of WordPress. If you change it at the time of installation then use that one. You will find it in wp-config.php file.
Now “active_plugins” column appears and click on Edit and see the “option_value”.
You will see something like this.
a:2:{i:0;s:19:”akismet/akismet.php”;i:1;s:9:”hello.php”;}
Here
a:2 represents how many plugins are activate
i:0 represents serial number of that plugin.
s:19 represents the length of akismet/akismet.php.
Now I want to activate “zm-ajax-login-register” plugin.
So I insert below value to option_value column and click on go.
a:3:{i:0;s:19:”akismet/akismet.php”;i:1;s:9:”hello.php”;i:2;s:33:”zm-ajax-login-register/plugin.php”;}
Wow! I activate the “zm-ajax-login-register” plugin.
You can also try to active “wishlist member” plugin.
Hello @uditkhanna. Please let me know what the result is.
