FontAwesome v4-shims.min.js break sites

Hi,

Please send me a link to your site so I can check this further,

v4-shims.min.js is a script that is meant to control the version update of font-awesome.
It shouldn’t cause any issues with your site.

Have you gone over our manual regarding update issues?
https://docs.elementor.com/article/235-update-issues

I hope this guide helped you solve this issue.

Hi @davidr90!

Site is https://www.friulmdservice.it/.

Update Elementor to version 2.8.1 a few minutes ago.
Same problem: Autoptimize javascript error.

SyntaxError: redeclaration of let l 
note: Previously declared at line 49, column 371

I have recompiled the file v4-shims.min.js with Closure Compiler service and replaced the original v4-shims.min.js with it.

After replacement everything is working properly.

Before replacement:

Hi,

Have you tried updating to version 2.8.2? do you still see any layout issues with your site?

Hi @davidr90 !

Same problem with version 2.8.2 and also with version 2.8.3 installed a few minutes ago…

As already explained also on https://github.com/elementor/elementor/issues/9805#issuecomment-565361491, the problem seems to be due to the incorrect compression of the v4-shims.js file.

Compressing this file with Closure Compiler and replacing the original compressede one with it everything works correctly again.

Problem is due to a variables redeclaration and is a problem of the package generated by FontAwesome, not an Elementor problem!

I downloaded the FontAwesome package and checked the v4-shims.js and v4-shims.min.js files.

v4-shims.js start as a function expression (IIFE) while v4-shims.min.js starts with the definition of two variables and this causes the problem.

Recompiling file with Closure Compiler (based on v4-shims.js) also v4-shims.min.js start as a function expression (IIFE) and everything works again ??

That’s all!
