Hey there,

I’ve been throughout all your threads for this issue and cannot seem to pinpoint the problem. A client has an event tomorrow evening and I cannot get either the Android app or the iOS app to co-operate. I can see the API results, claims success… but the apps won’t log in. I’ve increased server memory limit to 256MB and everything. My config is below. please advise 🙂

Hi Josh,

I checked your site and viewed the page source in the browser, as well as the json api public link and I’m seeing some unusual whitespace being output before any content. Here’s a screenshot with the whitespace outlined in pink.

That whitespace may be contributing to the errors you are seeing. The quickest way to find out what could be adding the whitespace is by temporarily switching to a default WordPress theme and deactivating all non – Event Espresso plugins, then check again.
