I'm trying to make a website that accepts the nano cryptocurrency and I've encountered an error. I'm using woocomerce+brainblocks plugin and whenever I tested paying with nano it did not show up in woocomerce dashboard under orders. I looked at my error log and I got the following:

Warning: call_user_func_array() expects parameter 1 to be a valid callback, function 'brainblocks_token_query' not found or invalid function name in /home/u598547570/domains/nanoid.store/public_html/wp-includes/class-wp-hook.php on line 286

I've contacted the brainblock developers about this bug and they said they'd look into it, but I don't know how long they'll take to fix it. Its there any way I could fix it myself?
