After some recent updates to my site, including the BoildGrod Pavillion template to 2.6.4. However after one of these upgrades the main pages were misaligned(became left justified, instead of center justified)
I eventually identified the bug on Pavilion/base.php line 40 as follows;
This <main class=”main <?php echo BoldGrid::print_container_class( ‘blog’ ); ?>”>
becomes
<main class=”main “>
instead of
<main class=”main container”>
My workaround was to edit the base.php to fix the class. This fixes my site, but I am not sure what happens on the next upgrade
