I got no layour after install 1.6.1.
the page looks like this:
from log it said:
ERROR - 2024-03-02 19:28:13 --> Could not find the language line ""
The lanuague I choose is English, and from the Language folder seems under english folder , there is no file called form_validation_lang.php file ,compare with other language folder.
Yes, I downloaded .zip file from the webisite.
and I can see all the .css files and .js files.
However, I tried to install it few times, but still the same layout.
I think that your error message is causing the layout to break.
Go into 1 of the other language directories and copy form_validation_lang.php to the english directory. See if that clears up the error.
