During a routine update of SlideDeck I accidentally clicked something else. It kicked me out and I can't get into my login page to fix anything and this
[[Fatal error: Access to undeclared static property: SlideDeckPlugin::$st_namespace in /home4/imellif/public_html/wp-content/plugins/slidedeck2-developer/slidedeck2-tier30.php on line 50]]
is the message I'm getting. I am at a complete loss of what to do since it won't even let me back into my admin dashboard.
