Hi chaps.
@curtisa There are a few errors in the HTML and CSS code on the site. Things like the dropdown menu with "<<Guitar of the month entry/vote archive" will throw a wobbly on many devices. The less-than signs are 'unescaped' which is potentially why some browsers will stop processing or misinterpret information at that point. I'm a web developer so this is definitely the first place I'd start. If you must have those signs then try replacing them with <<
Happy to help by PM or email if you need it.
In the short term, to help browse the site as a user, you can either try installing another good browser (Chrome, Opera, Firefox, Brave) or using the browser menu to 'Request desktop site' or similar.
Edit - I noticed you have tried a few browsers but some are more forgiving than others.
