How do I alter this form to:  refresh same page if url is not /~login? 

Edit; answer was:
Code: [Select]
location.replace({.if|{.match|*~login|%url%.}|{:document.referrer:}|{:"%encoded-folder%":}.})

I think we can pass current page (%encoded-folder%) through urlvar (/~login?redirect=%2Fsome%2Ffolder%2F)
Then redirect in /~login page with javascript etc.

The compact version is caching-compatible so that you can go from/to cached content without confusing the login/logout buttons.

I want to remove the "New folder" button (so that no one can create folders).
In hfs.tpl I found and changed the lines:
Code: [Select]
[+special:strings]
option.newfolder=0
option.move=0
option.comment=0
option.rename=0

But it did not help!
The "New folder" button is there and creates a folder.
I edit the template file correctly - I change/add different elements and they change in the browser.
But for some reason option.newfolder is ignored.

If you remove the entire block {.if|{.can mkdir.}….} - then the button disappears…

But why is option.newfolder=0 not working?

HFS 2.4.0 RC7 build #319

The best way to 'catch' where this error was introduced, is to test each build backwards. First, my recommendation is making a backup of your config files .ini and .vfs, and then start testing builds: RC6, RC5, RC4, RC3, etc. until you find the working version. This way it is much easier to find where the bug is.

2.4 beta 2 - The option.newfolder=0 works fine
2.4 beta 3 - The option.newfolder=0 is ignored, "new folder" does not turn off

Thank you, I will check the source code this weekend, and try to fill a bug report on the next days. My free spare time is limited, so don't expect this to be fixed soon (and also, Rejetto is not actively working on v2.x branch). That said, your report is very appreciated.

» EDIT: I've found the problematic commit where this bug was introduced, HERE. We still need to analyze how to keep the improvements, but fix this issue. Please be patient, until we find a solution.
