1) Press F12 in chrome to see if there are any javascript errors in console.

2) Investigate server error log to see if there are any 500 errors in the logs.

Not translated log in your language.

 

Browse to the file translations and replace LOG IN authentication in your language

Same problem+ my solution:

 

- Problem: After update from 1.6.1.7 to 1.6.1.8 i can't access to my BO: false css styles, and i can't access to BO even with entering correct logins (it gives an empty page)

- Attempts: So, after several attempts i noticed that this problem affects shops which are using an RTL language as default.

- Bug: bug on file: adminxxxxx/themes/default/css/admin-theme_rtl.css

- Test: i do a restore (returning to 1.6.1.7) i changed default language from RTL to LTR, then i have done the update to 1.6.1.8.

- Result of test: success, i can access to BO without problems.

I suscribe to this. After upgrading from prestashop 1.6.1.7 to 1.6.1.8, Romanian language is not working in backoffice, and I can't login in backoffice. I coud not even take my shop out from maintainance mode becouse it was impossible to acces BO. 

I solved the issue temporary, editting database for maintainance mode and language, but the Romanian language is still broken and unusable in backoffice.

Upgrading Romanian language pack is not working.. Error: Property Tab->name is empty

Manualy editing the translations seems to have an effect, but when I try to edit "Field name translation" for example, I get a 503 error - server is busy...

 

LE: Client e-mails for orders are also messed up.....

Fix:

Copy the Translations folder from a back-up and replace it via ftp on live site. All will come back to normal, so you won't need to roll back.

Looks that prestashop upgrade procces is messing up the language files...
