VanillaStats "Unable to Save" | Vanilla 3.3
Basically the title says it all, VanillaStats API credentials needed to be re-registered, but when I click Re-register API Key I'm met with another error which is "Unable to Save". I've tried the obvious, such as making sure my /conf/config.php is writable, but this seems to have made no difference.
Any suggestions would be great. Thanks!
