Uncaught SyntaxError: Unexpected token ‘


Im facing an error that not allow launch GTM.  The error is shown in the Browser console as: Uncaught SyntaxError: Unexpected token ‘<‘

As soon I disable Litespeed cache plugin, everything works fine.

I tried to exclude the js in litespeed cache but doesn’t work.

Location and js url are:

– /wp-content/litespeed/localres/7a40012a55d690ae256a69a8aaf9399b.js

– wp-content/litespeed/localres/aHR0cHM6Ly93d3cuZ29vZ2xldGFnbWFuYWdlci5jb20vZ3RtLmpz?id=GTM-N64FH626

I found that the script has an error 400:

I already try this: https://docs.litespeedtech.com/lscache/lscwp/ts-optimize/ and didnt solve the problem:

  • Using “/?LSCWP_CTRL=before_optm” in url, it solve the problem
  • Disabling CSS and JS optimization does not solve the issue.
  • Completely disabling the plugin, it solve the issue

Someone can help me with this issue?

Thanks in advance
