@ Samm – This appears to be a completely different problem than the Font Awesome problem so I have moved this to a relevant forum topic. Before troubleshooting anything else do these things below to see if they are causing the problems.
I see 2 things that could be a problem in general:
1. Your website is in Maintenance Mode using this plugin: Ultimate Coming Soon Page plugin.
– You may want to try taking the site out of Maintenance Mode to see if it is interfering with setting things up, etc.
2. From the Security Log entry it looks like you might be using minification or a minifying plugin.
– If you are using minification or a minifying plugin then you will not be able to use the BPS Pro Plugin Firewall and will have to deactivate it/turn it off. Or you can exclude all frontloading js scripts in your Minify plugin so that the Plugin Firewall will work correctly.
