Sometimes, when upgrading, installing, or enabling a module, one can lock oneself out of one's site, get a white-screen-o'-death, or otherwise render the site inaccessible. (Or so I've heard. I, um, have a "friend" who did this.)
It's pretty easy to disable the offending module in the database. You can do this using phpMyAdmin or a GUI Tool such as MySQL Query Browser.
- Log in to phpMyAdmin (using first your WebAuth credentials and then your database user name and password)
- Select your database
- Choose the system table from the menu on the left
- Click Browse (at the top of the main window)
- Click the pencil icon next to the offending module to edit it
- Change the status of the offending module from 1 to 0
- Be sure that Save is selected in the dropdown menu at the bottom, then click Go
- Breathe easy
Who knew turning modules on and off could be reduced to a binary operation?!?
