nitaish Posted March 3, 2020 Share Posted March 3, 2020 After upgrading WHMCS from version 7.9.1 to 7.9.2, we have started facing problems. We are unable to use the intelligent search as it throws 500 internal server errors with scripts.min.js of the V4 template. Also, when we try to download an invoice from the admin area, it leads to an error stating ERR_INVALID_RESPONSE. We created a support request with WHMCS, but they say there is some problem with the server configuration. We have not changed any server configuration and everything was working fine. The errors started occurring after we upgraded WHMCS. And surprisingly, there is no error shown in the error_log. We are clueless. Please help us to identify the cause of the issue and the resolution. 0 Quote Link to comment Share on other sites More sharing options...

nitaish Posted March 4, 2020 Author Share Posted March 4, 2020 The WHMCS was upgraded using automatic updater. We also replaced all the files from the files that we downloaded from WHMCS.com. The problem still persists. 0 Quote Link to comment Share on other sites More sharing options...

DennisHermannsen Posted March 4, 2020 Share Posted March 4, 2020 Doesn't it say anything in your website's error_log? 0 Quote Link to comment Share on other sites More sharing options...
nitaish Posted March 5, 2020 Author Share Posted March 5, 2020 The issue resolved finally. However, the solution is a little weird. We enabled Display errors and Log errors in WHMCS General Settings and saved it. Later we disabled them and saved again. This time it resolved the issue. 0 Quote Link to comment Share on other sites More sharing options...
