I was a bit confused because you mentioned the getCapabilities URL related to the ExceptionReport. The URL of the statusLocation (like <span style="color: #000000; font-family: arial, helvetica, sans-serif; font-size: 13.3333px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 1; word-spacing: 0px; -webkit-text-stroke-width: 0px; display: inline !important; float: none; background-color: #ffffff;">http://localhost/wps/3c7e38b6-06e0-11e6-8f17-0242ac190008.xml in your example) should not be handled by PyWPS at all. Could you define an other folder for the output files that is not related to /wps at all in your configuration file? Otherwise it would be useful to see your PyWPS config file and the config snippets from the webserver you are using.</span></div><div><span style="color: #000000; font-family: arial, helvetica, sans-serif; font-size: 13.3333px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 1; word-spacing: 0px; -webkit-text-stroke-width: 0px; display: inline !important; float: none; background-color: #ffffff;"><br></span></div><div>Cheers,</div><div>Jonas</div><div><span style="color: #000000; font-family: arial, helvetica, sans-serif; font-size: 13.3333px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: auto; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; widows: 1; word-spacing: 0px; -webkit-text-stroke-width: 0px; display: inline !important; float: none; background-color: #ffffff;"><br></span></div><span id="zwchr">----- Am 21.
