I went into the file where the error is and changed the following line of code at line 200 from
This:
add_filter( ‘upgrader_pre_download’, array( Tribe__PUE__Package_Handler::instance(), ‘filter_upgrader_pre_download’ ), 5, 3 );
To this:
//add_filter( ‘upgrader_pre_download’, array( Tribe__PUE__Package_Handler::instance(), ‘filter_upgrader_pre_download’ ), 5, 3 );
Just add to forward slashes to comment out the line of code causing this issue and it will start working again. At least until they get their crap figured out and fix it.
