Unable to access data after upgrade to 7.5.1.

:The upgrade went smoothly and SuiteCRM shows the current version to be 7.5.1. However, when I try to access accounts, leads, contacts, etc. I receive the message “There was an error processing your request, please try again later.” I have completed a repair and rebuild from the admin panel. Didn’t help.

Any suggestions? Thanks,

Looks like the update 7.5.1 was missing some files. For Leads here is the error:

require_once(custom/modules/Leads/LeadsListViewSmarty.php): failed to open st ream: No such file or directory in /var/www/html/area-vacations/suitecrm/custom/modules/Leads/views/view.list.php on line 4, referer: https://www.are a-vacations.com/suitecrm/index.php?action=ajaxui

On github page, found the sourecode for this missing file and manually created it from this
https://github.com/salesagility/SuiteCRM/blob/6ce83aa834f5b71791eab5914dd237b4492cf8ec/modules/Leads/LeadsListViewSmarty.php

It now works for Leads. Same thing required for targets, contacts, accounts, etc.
