How to restore login page

Hello Guys,

I was trying to customize my login page and made some changes to one of the scripts having external id "web.login". To test whether my changes were working, I logged out of my admin account expecting to be led to the login page. However, apparently there was some error in the code which I changed and now the login page is broken. It does not allow me to login at all showing a white page saying "Internal Server Error. The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application."

I know for a fact that this problem is caused by my changes to this script. I cannot revert the changes I made because I cannot login. My question is that is there a way to find this script (which is supposedly an xml file) through file explorer and revert the changes I made to it?

I am running Odoo v11 on a Windows 10 machine and have full access rights to the machine.

Thanks,

Mohammed

Edit : I cannot just update the web module because I have changed a lot of the views in it and this would destroy 4 months of work. I somehow need to reset just the code for the login page. Please give me any clue in this direction. It will be highly helpful and appreciated.

Ok guys. Finally solved it. For anyone stupid enough (as stupid as me) to land in the same mess, these are the steps to solve it.

1. Open the database using pgAdmin III
2. Login and navigate to Databases/Database_name/Schemas/public/Tables/ir_ui_view
3. Right-click and go to View Data/View All Rows
4. When the table opens up, navigate to the view that you messed up. In my case it was "web.login". Find this under the "key" column.
5. Go to the "arch_db" column where you will find the xml code that you changed. Double-click on the code and revert the changes that you made.
6. Save.

That should be it. However, be very careful not to change something other than what you intend to because it might mess up the system. Check if it fixes your issue and you are good to go.

Best of luck everyone!

Mohammed

Can you provide the logs? Maybe you could try to update Odoo so it would replace the inline edits and everything would go back to normal.
If you broke it after installing your custom mod you can simply remove or edit and upload the mod and restart Odoo - this should do a job

You may want to update the web module or even all modules by stopping the Odoo service and start Odoo from the command line by using the parameter -u all
