 * [12 years, 10 months ago](https://wordpress.org/support/topic/500-errorswhite-page/)
 * I’m having the same problems as this thread…[http://wordpress.org/support/topic/problem-with-memberships-pro-and-paypal-standard?replies=8](http://wordpress.org/support/topic/problem-with-memberships-pro-and-paypal-standard?replies=8)
 * But i think i can provide more information.
    One, the only account having this
   problem is a “free” account, not being charged. I think this might be what’s 
   causing this.
 * These are from the error logs off the site, WordPress debugging off, php error
   only.

 * Thanks for this. Someone else has been helping us with this and the next version(
   today or tomorrow) should address this. This info helps.
 * When the new version comes out, let me know if it clears things up or if you 
   are still having the issue.

 * Hi alpha1beta,
 * Have you tried the latest version (1.7.1)? This version should fix the 500 Errors/
   white page issue. Please let us know if everything is cleared up in the new version.
 * Thank You.
