In desperate need of some help here... my website http://www.glitterbugwallpaper.co.uk has been experiencing some problems now for over one week and I have tried everything I possible can.
I have recently uploaded some large photos to my website page as well as updating my theme and updating a plugin called WP Bakery Visual Composer, so im thinking one of these actions has caused the issue.
I can access my website from a desktop/laptop but it is really slow. Im unable to get access on a tablet or phone unless I turn off the plugin Visual Composer but when i turn this off the main construction of my site is replaced with code/text eg sliders and home page pictures.
Im also getting an error 500 to sometimes when loading on laptops and tablets.
I have access to the error logs but if im honest this makes no sense to me at all.
Any help would be much appreciated.
Thanks in advance
