Thank you for sending the url.
This is very odd. Earlier this afternoon I was able to replicate the problem as you described above. Then tonight I tried again and I am getting the Google Map to change along with the error that the address can’t be found. This indicates the problem is with the Sunlight Labs API…
Please make sure you have your Sunlight Labs API Key entered correctly in WP Admin > Settings > CongressLookup
Please try the following steps to help diagnose the problem:
PLUGIN CONFLICT: Please try deactivating all plugins except CongressLookup. If CongressLookup does then work, turn on one plugin at a time and test it again until you find the plugin it conflicts with. Please let us know what plugin this is. If, however, CongressLookup still doesn’t work when it’s the only plugin, then a conflict is not the problem.
THEME CONFLICT: Temporarily deactivate your premium theme and activate one of the default WP themes, like “Twenty Twelve”.
SERVER SETTINGS: Please tell the webmaster of the website to enable allow-url-fopen in php.ini
https://www.php.net/manual/en/filesystem.configuration.php#ini.allow-url-fopen
Also, disable the cache option for testing, then when allow-url-fopen is enabled and CongressLookup works then enable the cache again.
RESULTS: Please let me know the results of the above actions.
