not acceptable.. mod-security.. i can’t log in

Hi @majito, thanks reaching out to us.

Wordfence blocks are usually presented with a branded page containing our logo. This appears to be a plain server error citing the mod_security module as the cause.

I’ve found this, which might help you out, although you may still require assistance from your host: https://www.webtoffee.com/how-to-fix-the-mod_security-generated-error-on-your-site/

Thanks,
Peter.
