Hello,
This is due to your exchange not having enough history to show any data.
Please see “The [wallets_exchange_chart] shortcode does not display a chart.” under the troubleshooting section at https://www.dashed-slug.net/bitcoin-altcoin-wallets-wordpress-plugin/exchange-extension/
If you are facing any other issues that are unrelated to displaying the shortcode static templates, please open a new thread on the forums. Thank you!
with regards
