@rplante9176 No, but to be honest this plugin has never (at least to my knowledge) been tested on multisite. It doesn’t claim to support multisite, although if there are specific issues I’d attempt to fix them (and would love pull requests even more).
If you have a 500 error, though, you should have some server error logs that might point to what the issue is.
@rplante9176 we recently released a plugin update that fixed an issue some users encountered on servers without SOAP support. I’m not sure how common PHP installs without SOAP are, but it’s possible that was the issue you were encountering. I hope that will help, if so.
