After I updated the plugin, a sequence of errors began to occur on my site.
Among these errors, several special characters, the plugin can not login with an existing user.
Always returns the user or password does not exist.
I am also using WHMCS 5.1.2.
What should I do?
I'm leaving some printscreens for viewing the problem!
*Can not log a user that already exists
*When creating a new user, no problems, but there is still returning an error code.
