You can use the steps below to disable your plugins from within the database. This can be helpful if you can't access your WordPress dashboard.

Log into phpMyAdmin.

You can do so from your TsoHost Client Area account.

Navigate to Services -> My Services -> select the Managed WordPress service -> click on Login to Server

From the Dashboard navigate to Settings -> click on Show More next to phpMyAdmin click on View

Click on the wp_options table.

Locate the active_plugins entry under the option_name column. You may need to navigate beyond the first page of entries.

Click the Edit button for that row.

Select all of the text found in the option_value field, copy it, and paste it into a text editor.

Once the text was copied to a safe place, you can delete it from phpMyAdmin.

Click Go to submit the change.

You can re-enable your plugins at any time by editing the active_plugins entry again and pasting in the text you removed earlier.

Next steps:

If you disabled all of your plugins using the above method you can always enable them again from in WordPress.
