Hi,
Are you using a CDN? http://cdn.comsee-syrtsevka.savviihq.com
?
Can you disable all plugins so only Swift Framework and WooCommerce are active.
Please disable and then delete the plugin Swift Framework 1.66. Please then upload this zip file with the latest 1.7+ version: https://www.dropbox.com/s/v1an2fpylsvniqc/swift-framework.zip?dl=0.
When this is done, let me know and I’ll take another look, currently I cannot upload any fonts.
Thanks.
