Aug 2020 - WP Fix Stuff

My website is [login to view URL] Until recently it was working fine and needs a few things fixed. Please note this is a360 virtual tour site 1. When I want to edit any pages/post I get the following message "There has been a critical error on your website. Please check your site admin email inbox for instructions.". I need this resolved. 2. I have a portfolio of work and some clients host their 360 tours on their own server. Today I discovered that if I embed any of my past work that is not on my domain it doesn't go past the loading screen. For example on this page: [login to view URL] - that said if you load the URL directly it will work. This worked fine the last time I checked. This goes for all tours that I don't personally host. I need to embed the tours on my site. 3. HTTPS redirect. I have a plugin but it only kind of works. I want this plugin removed so that all my content is redirected to https which includes stuff that is not WP on my site like my virtual tours. Basically I want it in htaccess that redirects everything to https. You can not: 1. Uninstall/install plugins or change any of our security settings without us knowing beforehand... this will mean that we will cancel the job on you straight away. I need this done with 24 hours.
