cdonahue Posted July 19, 2019 Share Posted July 19, 2019 When attempting to login to a clients cpanel interface from WHMCS nothing appears to happen with a "... Working ..." pop that never completes. See attached When I view the apache log on the WHMCS server I see the following two entries when I click the "Login to cPanel" button: MYIP - - [19/Jul/2019:15:43:53 -0700] "POST /whmcs/admin/clientsservices.php HTTP/1.1" 500 153 [19/Jul/2019:15:43:53 -0700] MYIP TLSv1.2 ECDHE-RSA-AES128-GCM-SHA256 "POST /whmcs/admin/clientsservices.php HTTP/1.1" 153 The cPanel server has been added to WHMCS correctly using the API Token method, and I am able to access the WHM/cPanel page using the "Login to WHM" button. This error seems to have occurred after upgrading my WHMCS server from version 7.0.2 to version 7.4. 0 Quote Link to comment Share on other sites More sharing options...
WHMCS ChrisD Posted July 22, 2019 Share Posted July 22, 2019 Hi @cdonahue Thanks for your post on WHMCS.Community, are you seeing a pop-up blocker in the corner blocking the connection? I can see based on the logs is it calling out to the right place, do you get the issue in different browsers? If you open Google Developer Tools Console then try to click Login to cPanel do you get an error in there? 0 Quote Link to comment Share on other sites More sharing options...
cdonahue Posted July 22, 2019 Author Share Posted July 22, 2019 I've tested on Chrome, IE 11 and Firefox with the same results I don't see any popups In Chrome it shows one error message in developer console: POST https://whmcs.hostable.com/whmcs/admin/clientsservices.php 500 (Internal Server Error) scripts.min.js?v=5c7ed7:4 From a browser I am able to login to the cPanel interface directly using the users credentials listed in the WHMCS product tab. 0 Quote Link to comment Share on other sites More sharing options...

cdonahue Posted July 23, 2019 Author Share Posted July 23, 2019 Replacing admin/ includes/ and vendor/ with fresh copies has not fixed the error. I'm going to open a ticket with Support. 0 Quote Link to comment Share on other sites More sharing options...
