Application error 500 please help

Please help me with this error. Im using WordPress to build my website. I can’t access it.

BTW, error occurred after activation of W3 Total Cache plugin . I found the solution here but no idea where to acess the file. I can’t acess wordpress dashboard.

@sham Your Website works fine.

But don’t “https” because its gives SSL error.
If you want to use https then connect it with cloudflare.

Yeah already resolve it by deleting the plugin that cause the error from file manager and restoring the default .htacess

Thanks anyway
