Site not loading on desktop

Hi,

I was trying to run a plugin ‘Envira Gallery’ on my website and was facing some issues. I checked for error in browser using Inspect Element> Console and got below 2 errors for Envira Gallery:
– Mixed Content: The page at ‘https://www.fullonwedding.com/wedding-pre-wedding-photography-ideas-poses/’ was loaded over HTTPS, but requested an insecure stylesheet ‘https://www.fullonwedding.com/wp-content/uploads/2018/02/style-2016-07-19-10-56-41.css’. This request has been blocked; the content must be served over HTTPS.
– Mixed Content: The page at ‘https://www.fullonwedding.com/wedding-pre-wedding-photography-ideas-poses/’ was loaded over HTTPS, but requested an insecure stylesheet ‘https://www.fullonwedding.com/wp-content/uploads/js_composer/custom.css’. This request has been blocked; the content must be served over HTTPS.

To fix above error, I used Better Search Replace plugin and replaced the http URLs (in above errors) with https. But since then, front end of my website is not loading on desktop. Though it is working on mobile. And wp-admin of my website is also working.

PS: Below are the details of 2 replacements that I did using Better Search Replace:
1. Replaced https://www.fullonwedding.com/wp-content/uploads/2018/02/style-2016-07-19-10-56-41.css with https://www.fullonwedding.com/wp-content/uploads/2018/02/style-2016-07-19-10-56-41.css
2. Replaced https://www.fullonwedding.com/wp-content/uploads/js_composer/custom.css with https://www.fullonwedding.com/wp-content/uploads/js_composer/custom.css

Unfortunately I didn’t take database backup though I have latest code backup.

Please suggest what can I do to fix it.

Regards
