mobile view not sizing correctly and no slide out menu

[ColtSAA]

haven't edited this sight for a year but I opened it up on my iphoneX the main page is not sized properly and no slideout menu. the only thing ive done (after i saw this problem) was to change some background colors. I still have the problem in mobile view. i get one slim page, not the screen size i should be seeing and no slide-out menu anymore. i don't see any errors in the logs but it's not working as it should. the template is a cloned version of responsive_classic running v 1.5.6c URL: mountaingratitudedinner.org

figured it out all on my own

/includes/templates/MGD_Responsive_Template/common/tpl_header.php and tpl_main_page.php had somehow become corrupted. replaced with a local copy and it works!
