I've been using a google spreadsheet with my Visualizer plugin and I've never been able to get it to work directly from the 'publish to the web'/online csv file. However, it had been working fine with a downloaded file from my computer until this evening, when an error message suddenly appeared in my Visualizer media library page:
"allow_url_fopen option is disabled in your php.ini config. Please, enable it by change its value to 1. This option increases the speed of remote CSV uploading."
What does this mean? I can't seem to find a php.ini file. (Do you mean the config.php file?) My chart no longer appears on my site.
If possible, I'd also love to know how to fix the issue with the "From the Web" option so that my chart could automatically update from the google spreadsheet, but more than anything I just want it to work.
Let me know - thanks!
