Sometimes happens that you don’t have any backups of your WordPress site (ups) and after your plugins update nothing works (ups, twice!), especially /wp-admin/ got a blank screen with no reason. What to do? Deactivating all WordPress plugins through phpMyAdmin may help!
Step 1: Open your PHPMyAdmin and log in with your database credentials.
Step 2: Then select the right WordPress database and click on wp_options table.
The table is usually named wp_options, but you may use a different prefix. Look instead of wp_options to your prefix_options.
Step 3: Find active_plugins value in wp_options table.
Inside the wp_options table find in the column option_name row with value active_plugins. You probably need to go to the second page to find this entry. Once you find it, click the Edit button:
Step 4: enter a:0:{} in the option_value box and click Go
Done. All your WordPress plugins are deactivated. After that you may check again your admin URL (wp-admin) if it works.
