I've installed the plugin, and I've followed all of the instructions down to the point of creating the .htaccess files. I did click the AutoMagic buttons. I successfully activated the root htaccess file. But when I tried to activate the wp-admin .htaccess file, clicking the "Activate" button produced a popup window telling me I've chosen to open admin.php. I decided to upload an empty htaccess file into wp-admin and try backing that up first, but then when I went to the Backup & Restore tab and clicked the radio button for Backup .htaccess files and clicked the Backup Files button, I got a popup telling me I had chosen to open admin.php. Where do I go from here? I went to a few other tabs, and it seems that now every button I click in the BPS Pro admin section throws this same popup.
