Next to Upgrade from SuiteCRM 7.6.10 to 7.7.x or upper It's not posible to store emails address in any Module

Next to Upgrade from SuiteCRM 7.6.10 to 7.7.x or upper It’s not posible to store emails address in any Module like Leads and Contacts. In Edit Mode it seems to be able to do it but finally any email address is stored. The same problem occur when I try to modify an existent email address. I tried with the last five versions but it doesn’t work!!!
Is it necessary to upgrade the PHP Version?

CAN SOMEBODY HELPME!!

My SuiteCRM instance is running on:
Windows Server 2008
SuiteCRM: 7.6.10
PHP: 5.3.8
MySQL: 5.5.16
Apache: 2.0

I apreciate any help!!

Hello,

Can you share a screenshot of email address block?

Please check your PHP/Apache logs, the suitecrm/sugarcrm logs and the browser console.

We have the same problem on an updated SuiteCRM. Debugging shows that when storing an (inline edit) emailaddress the POST is formatted like this:

module:Home
action:saveHTMLField
field:email1
current_module:Employees
id:65080e36-435d-968d-f62a-599ab9a862cb
value:dsad@dsadsa.com
view:DetailView
parent_type:
to_pdf:true

On a test SuiteCRM where this problem does not occur, a POST of a similar action is formatted like this:

module:Home
action:saveHTMLField
field:email1
current_module:Employees
id:seed_jim_id 
value:jim@examples.com
view:DetailView
parent_type:
to_pdf:true

Perhaps suiteCRM tries to store the emailaddress as direct property of the (User/Contact/Employee) object in the broke case 1, while it should store in a separate object (probably referred to by ‘seed_jim_id’ in the working case 2.
