I REALLY NEED HELP. I had installed the WPLMS theme and started having problems logging in to WP and the menu sections disappearing. I started fresh, re-installed everything MAMP wordpress, the theme and started to work in WP installing the theme & plugins. Now the menu stays but if I click on a menu item and go to the section, the main part of the window is BLANK! I need someone to hold my hand and help me get going! I'm under tremendous pressure to move forward. I sent an email with my contact info. please help asap
