HTTP Ajax error when accessing panel pages or views [#2495185]

I've tried both the 7.x-2.0-alpha2 and 7.x-3.x-dev versions, and I am getting an http ajax error when trying to access views or panel pages. The error does not allow me to retrieve panel page information or modify a view. The error does not happen if I disable the simplesamplphp_auth module.
HTTP Result Code:200
Debugging information follows.
Path: /admin/structure/pages/ajax/operation/page-my-page-name/settings/basic
Status: OK

How is this related to this module? Could you describe the steps to reproduce?

Views and Panels work well if this module is not installed. The ajax error came up when I enabled this module. If I disabled the module, the ajax error did not come up, so I assumed that this module is the culprit. To reproduce the error, I just clicked any of the settings in a panel page: basic, access or menu.

And is your active user authenticated via SimpleSAML? Is there a difference in behaviour whether the user is authenticated or not? Are there any system errors on the status report (admin/reports/status)?

I tried authenticating a user via SimpleSAML, and I tried authenticating with a local Drupal account (set up under /admin/config/people/simplesamlphp_auth), and the Ajax error pops up in both occasions. I do not see any errors in the status report, except two warnings about the HTML purifier and Update notifications. Attached status report images.

Thank you so much for responding so quickly to the submitted issue. I found that a slash before the php tag in one of the simpleSAML configuration file was causing the Ajax error. I hope this post can help someone else.
