[SOLVED] White screen - Unable to display application screen after succesful login

We have recently upgraded to Projeqtor 6.2.5. After few days of use, I was working on customizing screens (with plugin 'Personnalisation des écrans') when occurred the issue. We did some server reboots and services restart but we still have the issue.

Issue: We launch the application and submit login: "Connexion acceptée"; but the screen becomes all white and nothing else appends. The behavior is equal on Firefox, Chrome and IE.

We found out that the Quotation.php was in error, with an extra comma : in attachement

Yes, now that problem has been solved but we still have an issue creating an order; and for taht one, I don't understand the log ....
